A roadside bomb struck a police van in Uruzgan province 370 km south of Kabul, leaving four commuters dead and another injured, spokesman for provincial administration Farid Ayel said Sunday. “The mine planted by militants targeted a police vehicle on a road in Uruzgan-e-Khas district yesterday evening, killing four and injuring another, “ Ayel said. He blamed Taliban militants for organizing the attack. However, the outfit fighting the government and largely relying on suicide attacks and roadside bombings has yet to make any comment.
