Gunmen attacked Teri Mengal High School in Pakistan's Upper Kurram tribal district, killing seven teachers who were on exam duty. The gunmen fled the scene of the attack and no group has claimed responsibility. Another teacher was also killed in a separate incident in the same district. Pakistani security forces had made multiple arrests two days earlier in the Khyber Pakhtunkhwa province where the attacks occurred. The Pakistani Taliban have increased their attacks in the country in recent months and renewed orders for terrorist attacks nationwide.
