Blast kills four peace keepers in Kabul
Four peace keepers have been killed and dozens injured in a bomb attack in Kabul.
The death toll thought might still rise, due to the severity of the injuries of those on the bus and Afgan on lookers.
The bus they were travelling was thrown off the road by the force of the blast from an apparent suicide bomb attack.
The peacekeepers, the majority of them German, were on route to the airport to return home after a six-month tour.
It is too early to know who was responsible for the attack, though local Afghan officials have said they believe it to be the work of Al Qaeda or Taleban remnants.
Anti government forces, believed to be Taleban, have been stepping up their attacks in recent weeks, with fighting in the south and east of Afghanistan.
The attack has been condemned by the German Chancellor and the Afghan authorities
