KALAYA: Suspected militants fired two rockets at a rally led by the governor of Pakistan's northwestern Khyber-Pakhtunkhwa province on Tuesday, killing one person and wounding four, but the governor was unhurt, security officials said.

Governor Masood Kasur was to address the tribesmen when the rally was attacked in Kalaya, a large town in the Pashtun tribal region of Orakzai, the officials said.

“The governor was receiving a briefing before the start of the function when the rockets struck. He is safe,” senior government official Fazal Qadir told Reuters.

“One rocket fell near the helipad while the other landed inside the ground where the rally was being held.”

Orakzai is one of the seven agencies of the Federally Administered Tribal Areas in the northwest. All but Orakzai shares a border with Afghanistan.

There was no claim of responsibility for the attack but Pakistani Taliban, who have been fighting to topple the US-backed government for years, operate in the area.

Pakistan has seen a wave of violence over the past years but militants have stepped up attacks since the death of al Qaeda chief Osama bin Laden in a secret US raid in a Pakistani town in May.
