A US drone strike in north-west Pakistan has killed two top commanders of one of Pakistan's most influential Taliban groups, officials say.
They say that among the four people killed is the brother of top Taliban leader Maulvi Nazir.
Maulvi Nazir's Taliban faction is based in Pakistan's South Waziristan tribal region where the drone attack on Thursday took place.
His forces are blamed for attacks on Nato troops in nearby Afghanistan.
The militants were killed when four missiles were fired at a pick-up truck they were driving in Azam Warsak, 20km (13 miles) west of Wana, the main town in South Waziristan.
Correspondents say that the strike is a sign that US intelligence has penetrated the close family circle of Maulvi Nazir. more
