MIRANSHAH, Pakistan: At least five militants were killed when their vehicle hit a roadside bomb apparently planted by a rival group in Pakistan’s troubled northwest, the Taleban and officials said Wednesday.

The bomb struck the vehicle of Amir Hamza, a local commander of the Sajna group in the remote Shaktoi area of South Waziristan tribal district late on Tuesday, killing him along with his four associates.

“A local commander of Sajna group and his four associates have been killed, they died on spot,” the local intelligence official told AFP. A militant source confirmed the incident.

The attack occurred five days after a cease-fire had supposedly ended a feud between supporters of commander Khan Said Sajna and followers of the late Hakimullah Mehsud in the tribal areas.
