Three suicide bombers have killed 20 people in an attack on a construction firm in southeastern Afghanistan.
The Interior Ministry says 50 other people were hurt in the attack, in the remote Bermel district of Paktika province.
It says the attackers forced their way into the firm's compound after killing a security guard and then detonated a truck packed with explosives.
The Taliban said it had carried out the attack, but that it had been on a military base and 49 foreign and Afghan troops died or were wounded.
