Afghan President Hamid Karzai in crucial US visit

President Hamid Karzai is due to arrive in the US on Tuesday for a visit that could decide the future of the US presence in Afghanistan.

His three-day trip will include a meeting with US President Barack Obama, at a time when correspondents say relations between the two countries have been more fractious than usual.

Mr Karzai wants US troops out of Afghan towns and villages.
