Drone strike kills 4 suspected militants in Pakistan

A U.S. drone strike in Pakistan's tribal region killed four suspected militants Wednesday night, two Pakistani intelligence sources and a local political official told CNN.

The officials said the unmanned aircraft fired two missiles at a vehicle near Anbar Shaga, a village 25 kilometers (15.5 miles) west of Miranshah in North Waziristan. It is one of seven districts in Pakistan's troubled tribal belt along the Afghan border.

The officials asked not to be named because they are not authorized to speak on the record. The United States has carried out 26 drone strikes this year, according to a CNN count. All have targeted North Waziristan or its border with South Waziristan.

U.S. officials normally do not comment on suspected drone strikes, which have caused tension between Pakistan and the United States in the past.
