NEW DELHI: A week before Pakistan's Special Investigation Team reaches Pathankot to probe the January attack, the National Investigation Agency (NIA) has released pictures of four alleged terrorists killed in the siege at the air base in Indian Punjab.

Through the release, the NIA hopes to get more information from Pakistani authorities on the four men, suspected to be the members of terror group Jaish-e-Muhammad, accused by India of attacking the Indian Air Force base on January 2 this year.

Seven security personnel and all six attackers were killed in the three-day siege.

India and Pakistan have agreed to conduct a joint investigation into the terror attack at the air base. The Pakistani probe team is expected to arrive in India on March 27 and the probe will begin the next day, India's External Affairs Minister Sushma Swaraj said last week.
