Pakistani officials say an American drone has fired four missiles at a compound in a troubled northwestern tribal region, killing at least 15 militants, AP reported.
Two intelligence officers say the strike happened on Wednesday morning in the town of in Datta Khel in North Waziristan, where the military last month launched a major operation against local and foreign militants who use the region to carry out attacks in Pakistan.
The officials spoke on condition of anonymity because they are not authorized to talk to the media.
U.S. drone strikes are a serious source of tension between Washington and Islamabad. The Pakistani government regularly denounces the strikes as a violation of the country's sovereignty.
