Pakistani jets bombed militant hideouts in a lawless tribal district on Saturday, killing scores of Uzbek and local insurgents in a massive ongoing offensive against the Taliban, the military said.
Air strikes were carried out at Miranshah, the main town of North Waziristan, and Boya village after shots were fired at troops, according to a statement.
"Five terrorists hideouts, caves and huge cache of arms and ammunition were destroyed and scores of terrorists killed in early morning strikes, silencing the firers," it said. "Most of the terrorists killed in strikes were Uzbeks," the statement added without providing casualty figures.
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. More than 500,000 people have fled the area with tens of thousands of families have leaving for the town of Bannu, close to North Waziristan.
Jets and artillery began hitting militant 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.
So far, 386 militants and 20 soldiers have been killed in the offensive, according to the military, though with the area off-limits to journalists the number and identity of the dead is impossible to verify.
Separately, a Pakistani solider was killed on Saturday by an improvised explosive device (IED) explosion during a clearance operation after the air strikes, the military said.
