A Pakistani military official says raids by security forces in the port city of Karachi have killed seven militants.
Brig. Gen. Mohammad Khurram told reporters Tuesday that the two overnight raids came after reports that militants from main Pakistani Taliban group planned to attack a security forces headquarters near the airport.
Khurram says that in the first raid, three militants were trapped in a building and killed themselves by detonating explosive vests.
He adds that in the second raid, security forces killed three militants while a fourth blew himself up.
After the Pakistani army began military operations in their tribal sanctuaries, many Taliban militants began hiding in urban areas.
