Kabul, Afghanistan ? A roadside blast struck a pickup truck Friday in southern Afghanistan, killing 14 villagers who were traveling to a provincial capital for holiday celebrations, an official said.

The explosion went off near a village five miles west of Tirin Kot, the capital of the province of Uruzgan. Capt. Andre Salloum, a spokesman for NATO’s International Security Assistance Force, said it was caused by an anti-tank mine, but it was not clear whether it was an old mine or newly planted by insurgents.

The victims from the village of Safid Shar had been traveling in the truck to Tirin Kot to celebrate the end of the Muslim holiday of Eid al-Fitr, said Abdul Qayum Qayumi, the governor’s spokesman.
