Pakistani military jets targeted hideouts in the Northwest near the border with Afghanistan early Sunday, killing at least 50 suspected terrorists, the military said.
Troops conducted airstrikes in North Waziristan based on intelligence about the presence of foreign and local militants who were linked to last week's deadly attack on the Karachi airport, the military said in a statement.
Most of the fatalities in the strikes were Uzbek fighters, the statement said. The raid took place in Degan and Datta Khel.
A separate statement said the attacks were part of a new offensive in North Wazirstan, where there has been a curfew since Friday evening. The offensive is called Zarb-e-Azb in Urdu, which translates to "Strike of the Prophet's Sword."
Pakistani Taliban sources said jets dropped five bombs on the Degan area. The target was a meeting of the Islamic Movement of Uzbekistan members, the militant group said, but added that the number of casualties is unclear.
Northwestern Pakistan is home to loosely governed tribal areas. It's also a base for foreign fighters and a refuge for members of the Islamist militant Haqqani movement.
Last week, the Islamic Movement of Uzbekistan claimed it carried out the airport attack, which resulted in an hours-long siege and left dozens dead, including the assailants. The militants said the attack was carried out with the Pakistani Taliban.
There were reports that travelers were congregating in hotels and restaurants in towns like Bannu after being stranded due to the curfew.
