PESHAWAR: Three Frontier Corps personnel were killed when a group of militants launched a rocket attack on a mountain fort in North Waziristan early Sunday, security officials said.
The midnight attack took place in the Spinwam area of the tribal agency on the Afghan border.
Officials said both military and paramilitary troops were inside the well-protected fort at the time.
"An unknown number of militants started firing rocket-propelled grenades from all sides. Three FC men embraced martyrdom when one of the rockets landed inside the fort," an official in Peshawar said.
The attack was apparently staged in revenge for the ongoing military operation Zarb-e-Azb, he added.
An intelligence official confirmed the attack and the casualties.
