PARACHINAR: Pakistani forces killed 11 militants and wounded 19 in the northwest on Friday, security officials said, in a crackdown in the Kurram tribal region near the border with Afghanistan.

The military fired artillery shells at three suspected hideouts in the Mamozai area of Kurram, where dozens of people have been killed in fierce fighting between Pakistani soldiers and insurgents in the last few weeks.

The death toll could not be independently verified and militants often dispute official accounts.

Pakistan's military has been conducting operations against militants in Kurram since the beginning of the year.
