A series of small bombs killed six people at a rally the Hindu nationalist leader held in the city of Patna on October 27.
Authorities said the home-grown Indian Mujahideen (IM) group was responsible. While Modi was not in the immediate vicinity of the explosions, the message was clear.
"Narendra Modi is way above everyone else on their hit list," said an officer in the Intelligence Bureau, who declined to be identified as he is not authorised to speak to the media.
"The IM cadre says he is actually 1 to 10 on their list. The rest come after that," said the officer, citing confessions of captured militants.
Modi will lead his Bharatiya Janata Party into a general election due by May and his enemies will almost certainly be looking for another opportunity to strike.
The militants hold Modi responsible for riots in 2002, during his first term as chief minister of Gujarat state, in which at least 1,000 people, most of them Muslims, were killed.
Modi denies any role in the riots or bias against minority Muslims.
Communal animosity has led to several high-profile assassinations in India, beginning months after independence when a Hindu fanatic gunned down Mahatma Gandhi, the leader of a non-violent struggle to throw off British rule.
Prime Minister Indira Gandhi, who was not related to Mahatma Gandhi, was killed by Sikh bodyguards in 1984 and her son, former Prime Minister Rajiv Gandhi, was killed by an ethnic Tamil suicide bomber in 1991.
The election is shaping up to be a highly charged clash with Modi and his aggressive Hindu nationalist supporters facing off against their Congress-led rivals, who say the vote is a fight to preserve India's secular foundations.
Much of the battle will be waged at public gatherings. Even in these days of 24-hour news channels and the Internet, Indian election campaigns hinge around rallies.
Modi will address countless throngs in coming months in his race against the Congress-led coalition which is expected to put up Rajiv Gandhi's son, Rahul Gandhi, as its prime ministerial candidate.
An elite team protecting Modi has been ordered to secure all public meetings using the same tactics of the Special Protection Group that guards former and serving prime ministers and their families along the lines of the US Secret Service.
Spotters in disguise will mingle in the crowds while an advance team will "sanitise" sites six times, the last time an hour before Modi's arrival, a security official said.
"Sewage pipes, manholes, you plug every hole in the ground and above," said the official.
Gandhi has spoken of the deaths of his father and grandmother and said recently he could be next to fall to the politics of hate. He is guarded by the top-level Special Protection Group.
An attack on either Modi or Gandhi could spark waves of reprisal violence.
"Rabid elements"
Modi, the three-time chief minister of Gujarat arouses strong passions among supporters and rivals. He is a hero of the Hindu right, and seen as a tough, business-friendly administrator who can help steady a nation in economic drift.
Critics accuse him of a deep-seated bias against Muslims and say he turned a blind eye to attacks during the 2002 riots. The Supreme Court absolved him of any wrongdoing.
The Indian Mujahideen allegedly has ties to Pakistan-based militants who have launched numerous attacks in India including the 2008 assault on several targets in the city of Mumbai.
Four days before the explosions at recent Patna rally, the Intelligence Bureau sent a letter to state authorities warning them of the threat to Modi, although they did not have specific information.
"Narendra Modi being perceived as a leader of Hindus, may be targeted by rabid elements," the bureau said. "Modi is also a target in the list of various terrorist organisations."
He is now protected by 108 Black Cat commandos of the National Security Guard (NSG), the anti-terrorism force that fought the militants who mounted the Mumbai attack.
Originally, Modi had a small NSG group trained to whisk him away in case of attack, a Home Ministry official said.
But his security has been stepped up and he now has three layers of protection: one group to take on any attackers, a second to provide cover and a third to get him to safety.
Ajay Sahni, head of the Delhi-based Institute of Conflict Management, said that given the rings of security, the chance of a direct attack on Modi or Gandhi was low.
"The inner core is very heavily protected," said Sahni, whose institute studies South Asian militant groups.
"It would be hard to penetrate unless the groups have the capacity to project explosives such as missiles. Those are difficult to smuggle around."
The biggest risk was the politicians themselves pushing against the security bubble as they bid to reach out to voters, Sahni said. Unlike in the West, powerful leaders in India at times overrule their security agents and wade into crowds.

@np: Well yes I live in Gujrat and unfortunately from a family that has suffered a lot from the riots. Without going into the details, we live in the country who has been dear to us, we contributed to its welfare but this what we get in return? Any body from where ever does something to my dear majority here and we get to suffer. For you (like the rest of Indians) it is just another riot that happened for a week or a month and that was it. Ask someone whose lives have been completely turned upside down permanently because we had leaders who were either involved and conveniently couldn't do to protect the suffering minority. Yes it is democracy and yes I still hold Modi responsible for all the suffering happened to me, my family and thousands of families like mine. Even if he was not involved (which I don't believe) he was still the man in charge. He is equally responsible for anything that happened in his jurisdiction if you really understand democracy! He couldn't protect minority in one state and you want to make him in-charge of the whole nation? Pity! and yes again, show some sense and reject RSS influenced pseudo extremists.
@A proud Indian Muslim: Have you heard any of Hafiz Saeed's speeches? HAve you herd any of Modi's speeches? Please show me any speech of Modi which is anti-Muslim? Please show me any policy in Gujarat which has been run by Modi for 11 years which is anti-Muslim.
When you say India will vote - are you not part of the India that will vote? SOmetimes you get the party in power that you want at other times you don't. That's how democracy rolls. What you are entitled to - regardless of who is in power is to be treated fairly by the state irrespective of who is in power.
ET, the title takes you to the level of 'The Nation'. The following link is for your reading pleasure which may open your ignorant eyes

@Bashir: That did not happen in Gujarat where he won 3 elections in a row. Why do you suppose that would happen nationally?
Shame on you ET for the tittle. You can spew your venom in the editorial if you want.
Its a shame that Mr. Modi has been brought forward to run for India's PM. A person whose speeches have everything but objectivity when it comes to Muslims or Pakistan. It is as if Pakistanis rally for Hafiz Saeed for PM. Both hate their next door neighbor. Both have been accused for hate mongering as well as calling for war. One has terrorist like accusations, the other has riots like accusations. One showed great economic & administrative performance in Gujrat, the other runs Pakistan's biggest and most effective charity & disaster rehabilitation programs.. To me, imagining both of them to be on top positions is calling for disaster. Show some sense India!
If he wins. India shall head towards further divisions. Social, cultural.. Who knows what else.
Annoying trend. I can imagine how annoyed Pakistanis would be if every time there was as reference to Imran Khan, it was preceded by terrorist sympathizer.
he is not divisive leader...he is the future of India...we are fed up with scams and mismanagement of congress..and for god sake we don't want congress to be in power for 2014. modi is an able administrator and in any of his speech he never mentioned of divisivness or doesn't indicate to do so..his focus is only on development and country first...but this nalayak congress cannot digest about..they always want people to have fear and be dependent on politicians so that their vote bank is secure..so started to create rumours...Congress is in fact communal than BJP..they are always responsible for communal tension due to their vote bank politics......

All candidates are divisive. If there was one that was not divisive, then he would get 100% of votes. The difference is that in some cases the candidates themselves say things which differentiate between people of different fait. At other times, vested interests create the divisiveness.
The maturity of the Democracy demands that no harm is done either to Mr Modi or to Mr Gandhi, and whatever the provocations, peace and harmony must be maintained. The bureaucracy must display their professionalism and patriotism by taking order only from the Constitution, whatever the cost, before the electors take their final call at the booth.
Your caption of the story is too irresponsible. Change it immediately or remove it, as you are not supposed to term him divisive. Who are u term him so ! U probably want to sensationalize the article by your reckless caption !
A biased article. What else can you expect from a Pakistani newspaper? "Hindu fanatic gunned down Mahatma Gandhi". The choice of your words is exactly what makes me jump with joy when I hear the words "Muslim terrorist" countless times in the news.
Your understandin of Mr.Modi could have been better ! Do not take Indian medias one sided conclusions ! Always truth is a bitter pill ! He is actually above all politicians in making the administration fair !
You are calling Mr Modi "divisive", and this comes from a country which divided in two in 1971 and is facing right now a similar threat with regard to Baluchistan.
Your news report on Narendra Modi has many factual errors. Mahatma Gandhi's assassination is noway related to his assassin being Hindu. Mahatma Gandhi was killed for political reasons not for any religion related matter. The then Congress party tried to make religion-stamp on Mahatma's assassination, but the committee of investigation set up by this very Congress party established Gandhi's assassination as a political one. Vir Savarkar a Hindu activist & friend of Godse (Gandhi's assassin) arrested by Congress ruled Government had to be released after the committee's report.
The 2002 communal riots of Gujarat are result of burning alive of Hindu religious workers traveling in a train compartment by Muslim mobs. Communal riots have occurred in India many times before & after Gujarat riots and it is our experience that lakhs of people get involved in these riots and no chief minister could anything as police has very small man power in India. Besides the special investigative team set up to investigate Gujarat riots exonerated Mr.Modi.
Narendra Modi is not divisive. In the latest elections to state assembly his party candidate has won election in a Muslim strong hold constituency, Godhra!
Both Islam & Christianity are foreign religions to India. Indians never went out of their country to war and convert forcibly people of any foreign land. Indians lived peacefully with multiple religions for centuries until these two, the Muslims & the Christians came to India. Since the entry of these two there is no peace here!!
He will lead India for a better future. Not a divisive personality but a decisive personality for the enemies of India
He is not a divisive candidate. Talking oneness of a country is not divisive activity.
Please change your headings "India throws rings of protection around divisive candidate Modi" Modi is not a divisive he is Decisive candidate.
