SHARAN, Afghanistan, (AFP) - Three suicide bombers rammed an explosives-laden truck into a construction depot in eastern Afghanistan, killing 24 workers and wounding 59 others, officials said Monday. The bombers forced their way into the privately-run construction facility in Paktika province by shooting a security guard dead before blowing up their truck late Sunday, the interior ministry said. The provincial administration condemned the attack in Barmal district, which shares a long, porous border with Pakistani areas. At around 8:20 pm, a truck filled with explosives entered the complex and detonated, it said in a statement. Based on the information we have, 24 people were killed and 59 others were wounded. President Hamid Karzai said the attack was unforgivable, calling it the work of enemies of Afghanistan who oppose the countrys development. Taliban spokesman Zabihullah Mujahid said the group was responsible for the attack.
