An explosion rocked Obe district in western Herat province, 640 km west of Afghan capital Kabul, killing 14 people and wounding 11 others on Thursday, a spokesman for the provincial governor said.

"The tragic incident occurred at around 09:00 a.m. local time when a mine planted by terrorists on the road struck a mini-bus in Obe district. As a result 14 people, all civilians, were killed and 11 others sustained injuries," Mohidin Nuri told Xinhua.

Women and children are among those killed and injured in the blast, he said.

Nuri also blamed the enemies of peace, a term used by Afghan officials against Taliban militants, but the outfit fighting Afghan and NATO-led troops has yet to make comment.
