At least 23 militants have been killed in fighting between pro-government tribesmen and Taliban insurgents in north-west Pakistan, officials say.
The clashes took place in Ambar village in the lawless Mohmand tribal region, bordering Afghanistan's Kunar province.
Mohmand in North-West Frontier Province is said to be a hub for Taliban.
In the neighbouring Khyber tribal area, militants attacked a tanker carrying fuel for Nato forces in Afghanistan. Two people died in the attack.
