In a 55-minute video posted online, Zawahri also renewed a longstanding vow of loyalty to Afghan Taliban leader Mullah Omar, in an apparent snub to the Islamic State armed group challenging al Qaeda for leadership of transnational Islamist militancy.
Zawahri described the formation of "Al Qaeda in the Indian Subcontinent" as a glad tidings for Muslims "in Burma, Bangladesh, Assam, Gujurat, Ahmedabad, and Kashmir" and said the new wing would rescue Muslims there from injustice and oppression.
Counter-terrorism experts say al Qaeda's ageing leaders are struggling to compete for recruits with Islamic State, which has galvanised young followers around the world by carving out tracts of territory across the Iraq-Syria border.
Islamic State leader Abu Abu Bakr al-Baghdadi calls himself a "caliph" or head of state and has demanded the loyalty of all Muslims.
The group fell out with Zawahri in 2013 over its expansion into Syria, where Baghdadi's followers have carried out beheadings, crucifixions, and mass executions.
As well being an indirect repudiation of Islamic State, the announcement could pose a challenge to India's new prime minister, Narendra Modi. He has already faced criticism for remaining silent about several incidents deemed anti-Muslim, underscoring fears that his Hindu nationalist followers will upset religious relations in the majority Hindu nation.
However, while al Qaeda is very much at home in the Afghanistan-Pakistan border area, due to influential contacts and a long presence there, it is a minnow compared to local militant groups in terms of manpower and regional knowledge.
SAFE HAVEN
Over the years Zawahri and his predecessor Osama bin Laden, killed by U.S. forces in 2011, repeatedly pledged allegiance to Mullah Omar, in return for the safe haven he granted their followers in Afghanistan.
The statement did not mention Islamic State or Baghdadi, but it appear to take a subtle dig at the group's efforts at administering areas it has seized in Iraq and Syria.
Islamic State's effort at state-building is something never attempted by al Qaeda's central leaders, who traditionally have preferred to plot complex attacks on targets in the West.
Zawahri called for unity among militants and criticised "discord" - echoing a common al Qaeda complaint against Islamic State's record of clashing with rival Islamist groups in Syria.
The statement also warned al Qaeda's new wing against oppressing local populations - another complaint levelled against Islamic State by critics in Iraq and Syria.
"If you said that you are doing jihad to defend the sanctities of the Muslims, then you must not transgress against them or their money or honour, and not even transgress your mujahideen brothers by word and action," he said.
"Discord is a curse and torment, and disgrace for the believers and glory for the disbelievers," he said. "If you say that by your jihad you do not want but the pleasure of Allah, then you must not race for governance and leadership at the first opportunity."
Muslims account for 15 percent of Indians but, numbering an estimated 175 million, theirs is the third-largest Muslim population in the world.

Please remember we Muslims in India feel safe than anywhere in the world because we all live together like brothers. There may be a few extreme cases but definately the feeling is not scary like living in Syria, Libiya, Iraq, Iran or Pakistan. Do not even try to corrupt our minds because you will not succeed and will die like rats. We all Indians will fight together to keep the Talibani mentality away from India. The best county to live safely and prosper for any Muslim is India today.
I pity the T, LeT , IM and the one and only AQ. They look so puny and insignificant in front of their big brother ISIS. Gosh how time changes. I think for these groups now , its time to shut the shop. Please go home little ones. Games over. Ta.
