Pakistan’s military accuses neighboring India of sponsoring militants in the restive southwestern Balochistan province, which saw an unprecedented attack this week by armed separatists.

Nearly 350 hostages have been rescued at the end of a deadly standoff between Pakistan’s military and armed militants who hijacked a train in the southwestern Pakistani province of Balochistan, a security source told CNN Wednesday.

Baloch separatist militants blew up a railway track and launched rockets at the Jaffar Express, which was carrying over 400 passengers.
