The megalopolis has been in the grip of political and sectarian violence between majority Sunni Muslims and minority Shias, and the arrests come just days before the start of Muharram.
Mohammad Aslam Khan, the head of the police anti-extremism cell in southern Sindh province, said the four were members of Lashkar-e-Jhangvi, a banned Sunni militant group blamed for many deadly attacks on Shias.
Khan said the men were planning strikes during Muharram, when Shiites hold public processions, and police had seized at least 25 kilos of explosives, along with grenades, automatic rifles and pistols.
Of the 40 or so killed in the city of 18 million people over the past three days, 24 were in sectarian or political violence, Khan said. More than half of the victims were Shia.
"The objective of this wave of target killings was to spread sectarian strife in the city as a prelude to Muharram," Khan told AFP.
Lashkar-e-Jhangvi is regarded as the most extreme Sunni terror group in Pakistan and is accused of killing hundreds of Shias since its emergence in the early 1990s.
It developed close ties to al Qaeda and the Taliban, which ruled in Afghanistan from 1996 until the 2001 US-led invasion.
Pakistan formally banned the group in 2001 and there have been numerous crackdowns with arrests and killings of known Jhangvi operatives over the last 20 years.
A spokesperson for the government paramilitary Rangers told AFP on Tuesday that troops arrested 23 other suspects across the city, including an alleged "notorious" target killer, in a bid to stop targeted killing.
Earlier in the day, the Sindh Rangers carried out targeted operations in nine different areas of Karachi on Tuesday after a week of continuing violence, reported Express News on Tuesday.
Around 53 suspects were arrested during the operations and ammunition was recovered from them.
According to Rangers spokesperson, operations were carried out in Bilal Colony, Shamsi Society, Model Colony, Gulshan-e-Maymar, Awami Colony and Liaquatabad among other areas.
One target killer, Shamsur Rehman, was also arrested during a raid.
According to the police record, around 80 people have been killed in the city in just 10 days. Targeted killings in the city have left over 1,850 people dead in Karachi this year alone .
On Monday, two workers of a religious outfit and two political activists, among 10 people, fell victim to drive-by shootings, while Rangers and police claimed to have arrested more than two dozen suspects during raids in different areas.

Rangers are now a part of the prob in khi
Its time for Rangers to carry out operations in there own HQ.
Do not blame judiciary on such issues....you guys seem to be unaware ( wittingly or unwittingly ) that our judicial system are running on old British / Indian criminal codes & its is the responsibility of the MPs / Parliament to amend these outdated criminal codes & frame new laws especially relating to " terrorism "...our investigation wing in police is outdated & cannot match the modern way of investigation bcz 1) the police force is politicised 2) our police force hv very low education,hence, very low analytical qualities 3) these terrorists / criminals hv political backings 5) we have no witness protection program to protect witnesses who live in fear for the lives of his family ( read, the last witness in Wali Khan murder also killed in absence of witness program wherein important witnesses & their families are provided protection till the case is resolved ). Under these circumstances, blaming the judiciary is unfair & bit too much.Without understanding our shortcomings, just bashing judiciary seem to have become a new fashion trend in Pakistan....
i think results are more important then arrest. no of arrest are been made previously as well.
The arrests are there ok but then what happens next, you leave them out on bail and next we loose track of them???
The system in our country is totally messed up, it's important to put more emphasis on revitalizing the way we organize first.
Very soon Bar will provide them with the legal support and Bench will release all these criminals. What could be better business than crises for such professions. End of the day, things will be at square one.
