PARACHINAR, Pakistan — Pakistani security officials say a U.S. drone has fired four missiles at a compound of militant commander in a northwestern tribal region, killing 10 militants.

The officials said at least 15 insurgents were wounded in Thursday's strike in Orakzai tribal region.

They said the dead and wounded men were fighters led by a militant commander, Hafiz Gul Bahadur, who is based in North Waziristan.

The officials spokes on condition of anonymity as they were not authorized to speak to reporters.

Pakistan has often criticized the U.S. drone strikes.

Although U.S. forces often target militant hideouts in the country's north and south tribal regions bordering Afghanistan, airstrikes in the Orakzai area are rare.
