Kabul: The death toll in a powerful suicide truck bombing that struck a guest house in eastern Afghanistan rose to 21 with as many as 90 others wounded, officials said Saturday.
No one immediately claimed responsibility for the late Friday night bombing in Pul-e-Alam, the capital of Logar province.
There was no indication why the guest house was targeted.
In Afghanistan, guest houses are lodgings often provided for free by the government, usually for the poor, travellers and students.
The Interior Ministry quickly blamed the Taliban. There was no immediate response from the Taliban.
The attack came on the eve of the official date set for the start of the final withdrawal of US and NATO troops from Afghanistan.
The Taliban, who had demanded that all US troops pull out of Afghanistan by May 1, have not offered any guarantees for the safety of the departing troops.
There was no indication the bombing was connected to the pullout and there are no US or NATO troops in Logar province.
Hasib Stanikzai, head of the Logar provincial council, said that at the time of the attack, a group of local police were staying at the guest house, waiting for transportation home.
Other rooms were occupied by students from more remote districts who had come to the provincial capital for university entrance exams.
Interior Ministry spokesman Tariq Arian said the attack was under investigation and that the roof of the guesthouse had collapsed in the bombing. There were fears bodies could be trapped beneath the rubble, he said.
After 20 years, Washington is ending its forever war in Afghanistan. Starting on Saturday, the last remaining 2,500 to 3,500 American troops will begin leaving the country, to be fully out by September 11 at the latest.
The pullout comes amid a resurgent Taliban, who control or hold sway over half of Afghanistan. (AP)
