India indicts JeM chief Masood Azhar over Pathankot attack

India's top counter-terrorism agency on Monday charged Jaish-e-Mohammad (JeM), and its top leader, with perpetrating a deadly attack on an Indian air force base in January.

The National Investigation Agency (NIA) stated that all four gunmen who stormed the air base on Jan 2 were Pakistani nationals and that Maulana Masood Azhar, the top leader of JeM, was the mastermind behind the attack.

 "All the terrorists are accused of waging war against India. This was a criminal conspiracy to attack our security infrastructure," said a senior official at the NIA in New Delhi.

The presentation of a charge-sheet to a trial court wraps up India's investigation into the 18-hour siege at the Pathankot air base in which seven Indian security personnel and the four assailants were killed.

The attack, which came a week after Indian Prime Minister Narendra Modi paid an impromptu visit to his Pakistani counterpart, Nawaz Sharif, derailed a tentative thaw between the nuclear-armed rivals.

A joint investigation into the attack went nowhere and tension between the neighbors has risen over the course of a year marked by protests and cross-border clashes in the disputed region of Kashmir.

Investigators in New Delhi said the charge-sheet and evidence would be offered to Pakistani authorities to take action against the perpetrators of the attack. "We want Pakistan to arrest Maulana

Masood Azhar and he should be deported to India," said a senior Indian home ministry official who is overseeing the investigation.

The charge-sheet cited DNA samples, food packets from Pakistan found in woodlands near the air base, a walkie-talkie set and a note found in a car used by the militants to drive to the base.

India has long accused Pakistan of using Jaish-e-Mohammad as a proxy to mount attacks on Indian soil and had earlier given what it called "actionable intelligence" to Pakistan, including telephone intercepts.
