Cricketer-turned politician Imran Khan’s Pakistan Tehreek-e-Insaf party on Thursday condemned the drone attack in the country’s northwest Hangu district and termed it as a “declaration of war” by the U.S.

“This was a declaration of war against the people of Pakistan by the US,” party’s chief spokesperson Shireen Mazari said in a statement.

The party plans to hold a sit-in on Saturday to block NATO supply trucks running though Khyber Pakhtunkhwa province which it rules.

Mr. Mazari “demanded to know whether the Pakistan government and military were sleeping while Pakistan was being attacked or were they complicit in this latest drone attack?”

She said the time had come for the Pakistan government to demonstrate through actions that there is zero tolerance for drone attacks amongst the people and political leadership of Pakistan — a consensus reflected in the APC resolution.

A U.S. drone strike targeting a seminary in Hangu district’s Tal area on Thursday killed at least eight persons and injured five others.
