A U.S. drone has crashed in Pakistan's North Waziristan region near the border with Afghanistan.

The unmanned aircraft crashed in the mountainous area of Machikhel late Saturday.

Taliban members have claimed they shot down the drone, but neither the U.S. nor the Pakistani government has confirmed that.

The United States uses drone strikes to target Taliban and al-Qaida militants inside Pakistan. The drone program is unpopular with the Pakistani people, who say it is a violation of sovereignty and a threat to civilians.
