The Associated Press reports: The Pakistani government has demanded the U.S. vacate an air base within 15 days that the CIA is suspected of using for unmanned drones.

The government issued the demand Saturday after NATO helicopters and jet fighters allegedly attacked two Pakistan army posts along the Afghan border, killing 24 Pakistani soldiers.

Islamabad outlined the demand in a statement it sent to reporters following an emergency defense committee meeting chaired by Pakistani Prime Minister Yousuf Raza Gilani.

Shamsi Air Base is in southwestern Baluchistan province. The U.S. is suspected of using the facility in the past to launch armed drones and observation aircraft to keep pressure on Taliban and al-Qaeda militants in Pakistan’s tribal region.
