Pakistan’s military said on Sunday that it had killed 54 militants trying to infiltrate the country from Afghanistan, highlighting the challenges its forces face on multiple fronts as tensions with India also rise rapidly.

The operation against the fighters from Afghanistan took place on Friday and Saturday nights in North Waziristan, a remote district along Pakistan’s northwestern border, its military said.

Pakistani troops detected the movement of the large group of militants and killed all of them, the military said, adding that it had seized a cache of weapons and explosives.
