At least 51 people have been killed in a collision between a bus and a truck in eastern Afghanistan.
Gen Zarawar Zahid, the police chief in Ghazni province, said both vehicles burned after the collision in Ab Band district.
He said 51 of the 56 passengers on the bus have died. Afghan police and soldiers are working to remove the victims, including children, from the wreckage.
He said many of the bodies were so badly burned that they cannot be easily identified.
The fate of the two drivers was not immediately known.
The collision occurred on a road that links the Afghan capital Kabul with Kandahar, the largest city in the south.
"It is very sad," Gen Zahid said of the tragic accident. "When you see the bodies, some of them are not recognisable."
He added that the cause of the crash had not yet been determined but he ruled out the possibility of an attack.
Meanwhile, a spokesman for Paktika province said six civilians died after the tractor they were travelling in hit a roadside mine. The official said the civilians were returning home from collecting firewood in the mountains when they struck the bomb in Khoshamand district.
Separately, the US-led military coalition said a Nato service member was killed yesterday during an insurgent attack in eastern Afghanistan. No other details were released about the death.
