The Afghan president must set up a "major crimes tribunal" and an anti-corruption commission, US Secretary of State Hillary Clinton says. She told ABC television that Hamid Karzai "can do better". The Afghan leader - recently re-elected in a poll marred by fraud allegations - has come under growing Western pressure to deal with corruption. One of Mr Karzai's spokesmen insisted the Afghan leader's administration was "serious" about tackling corruption. The American ambassador in Kabul has warned against a US troop surge unless Mr Karzai takes action against corruption.
