Four militants were killed and several were injured Tuesday night in a U.S. drone strike in Pakistan's tribal region, two Pakistani intelligence officials and a local government official told CNN.
The officials said the drone fired two missiles at a target in Machis, a village near Miranshah in North Waziristan, one of seven districts in Pakistan's tribal region bordering Afghanistan.
A count by the CNN Islamabad bureau found there have been 22 drone strikes in the tribal region this year. All have targeted locations in North Waziristan or near its border with South Waziristan.
The officials asked not to be identified because they are not authorized to speak to the media.
