Pakistani intelligence officials say a suspected U.S. drone strike targeting a militant hideout killed six men in a northwestern tribal region along Afghan border.

The two officials say the compound hit late Tuesday in the Shawal area of North Waziristan belonged to Islamic militants loyal to an Afghan warlord and was also frequented by Uzbek fighters.

They spoke on condition of anonymity because they were not authorized to talk to the media.

The officials say the identity of those killed has not yet been determined.

The Pakistani military has been battling militants in Shawal as part of an offensive launched in June 2014 in North Waziristan, a longtime stronghold of al-Qaida and other armed groups.
