A roadside bomb has killed six Taliban militants, including a prominent local commander, in north-western Pakistan in an attack that could have been motivated by tensions between different insurgent groups.
The bomb was detonated by remote control as Hakim Khan and five lower ranking militants were driving through the town of Marindy in the Kurram tribal region, said Jamil Khan, a local administrator.
The commander who was killed was suspected of attacking Pakistani troops and kidnapping people for ransom, he said.
It was unclear who carried out the attack, but rivalries between different groups of fighters in north-western Pakistan sometimes escalate into violence.
The commander who was killed was from Kurram but had close ties to the Pakistani Taliban, an umbrella group of militants based in nearby North and South Waziristan, Mr Khan said.
