In pictures: Afghans fear US backlash

Thousands of Afghans have been trying to flee their country fearing imminent US reprisals for last week's terror attacks - but neighbouring Pakistan and Iran, already home to millions of Afghan refugees, have shut their borders.

People in Kabul have been stocking up on supplies fearful of US raids

Many have piled onto trucks and headed towards Pakistan

Others have packed up their belongings and are attempting to escape on foot

Pakistan has, however, closed its border and says it will not allow any more refugees in

On the other side, many Afghans have gathered hoping they will be allowed to cross

But guards have been positioned to keep the boundary sealed, and the Afghans out

Those already in refugee camps in Pakistan fear what may be about to happen in their country
