MIRAMSHAH: Pakistani Taliban fired a mortar bomb at a military check post in the North Waziristan region on the Afghan border on Thursday but there were no casualties, intelligence officials said.

The attack happened near Miranmshah, the main town in the North Waziristan tribal region.

“It missed the post and we have no reports of any casualties,” an intelligence official in the region said.

The main market in the town closed down and security forces fired shots in the air after the attack, residents said.

Pakistan has seen a surge in violence since al Qaeda chief Osama bin Laden was killed in a US raid in a northern Pakistani town on May 2.

Pakistani Taliban militants allied with al Qaeda have vowed to avenge bin Laden's killing.

A suicide car bomber killed five policemen and a soldier in an attack on a police station in the main northwestern city of Peshawar on Wednesday.

Early this week, Taliban assaulted a heavily guarded naval base in Karachi that killed 10 military personnel and destroyed two aircraft.
