These men are loyal to Pakistan's most feared militant leader, Baitullah Mehsud. He recently gave the BBC and other news organisations rare access to his tribal stronghold in South Waziristan.
Mr Mehsud (back to the camera) does not like being photographed. He recently announced a ceasefire, but has warned that it will be jeopardised if the government "continues to be slaves to the US".
This man, Zulfiqar Mehsud, listens earnestly during a conversation with journalists. He is one the pro-Taleban faction's best-known fighters and is heir apparent to Baitullah Mehsud.

These rockets can in theory hit targets up to 20km (12.4 miles) away. So far most of these weapons have not been used since the ceasefire.
Increasingly, the ranks of Mr Mehsud's militia are filled by young recruits. Hamza, a 13-year-old, has been fighting since he was six. He says he's wanted by the authorities for killing security personnel.

Mr Mehsud's fighters span a wide range of ages and are more than happy to pose for photos. All pay homage to "Amir Sahib" (honoured leader) - as Baitullah Mehsud is affectionately called by his men.
The militants operate in some of the most beautiful countryside in South Waziristan, with towering mountains, clear flowing streams and lush green valleys dominating the landscape.
