Bannu, Pakistan: Pakistani jets and artillery pounded militant hideouts in a lawless tribal district, killing 18 foreign and local insurgents in a massive ongoing offensive against the Taliban, officials said on Sunday.

Air strikes were carried out in Mosaki area, 25 kilometres east of Miranshah, the main town of North Waziristan, on Sunday while artillery shelled militant hideouts in Kharkamar area, 30 kilometres west of Miranshah on Saturday night.

“Six terrorist hideouts and a huge ammunition cache were destroyed and at least 13 militants, most of them Uzbeks, were killed in the Saturday morning strikes,” a security official told AFP.

He said five other insurgents were killed and two militant hideouts destroyed by artillery fire in Kharkamar area on Saturday night.

A local intelligence official confirmed the raids and militant casualties.

A military statement also said that a number of terrorists were killed but did not give the exact number.

Last month Pakistan’s military launched a long-awaited offensive in North Waziristan, aimed at wiping out longstanding militant strongholds in the area, which borders Afghanistan.

Jets and artillery began hitting rebel targets on June 15 to try to regain full control of the district after years of pressure from Washington and other powers.

The assault was finally launched after a dramatic attack on Karachi airport which killed dozens of people and marked the end of a faltering peace process with the Pakistani Taliban.

More than 400 militants and 20 soldiers have been killed in the offensive so far, according to the military. The area is off-limits to journalists and the number and identity of the dead is impossible to verify.

The rugged mountainous area has for years been a hideout for Islamist militants of all stripes — including Al Qaida and the homegrown Tehreek-e-Taliban Pakistan as well as foreign fighters including Uzbeks and Uighurs.

The latest air strikes came a day after militants crossed from the Afghan province of Kunar to launch a pre-dawn ambush on a check post in Bajaur tribal district, killing three Pakistani soldiers.

“Pakistan lodged a strong protest with the Afghan side in Islamabad and Kabul on Saturday and reiterated that Afghanistan should eliminate the terrorist sanctuaries and not allow its territory to be used against Pakistan,” the foreign ministry said in a statement.
