A witness says 20 more bodies have been found at the site of a suspected U.S. missile strike in northwest Pakistan, bringing the death toll to 30.

Rehman Ullah was at the scene of the strike in Kurram tribal region. The missiles are believed to have destroyed a house used by a local Taliban commander.

The U.S. has launched a barrage of similar attacks against suspected militants in the border region using unmanned drones.

Pakistan has protested the strikes, saying they undercut civilian support for the fight against militants.

Ullah, a resident of the targeted village of Baggan, said drones were seen in the sky before the attack.
