The suspected militants were killed in two separate incidents since last night, a spokesman for the Paramilitary Rangers said.
"Four of them were killed in Janjal Goth while three were killed on the Northern Bypass when they opened fire on a Rangers patrolling party," he said.
In the first incident, four terrorists were killed after an exchange of fire with Rangers, who were conducting a search operation in a slum area.
In another incident three other terrorists were killed on the Northern Bypass when they did not stop near a Rangers check post and opened fire on a patrol party.
A senior official of the Rangers was also injured in the firing.
