A roadside bomb struck a tractor in the Yahya Khil district of Paktika province on Saturday, killing a civilian and injuring five others, spokesman for provincial administration Mukhlis Afghan said. "The tragic incident happened in Yahya Khil district at 07:00 a. m. local time and as a result the tractor driver was killed on the spot and five others including a mother and three children were injured," Mukhlis Afghan told Xinhua. The spokesman blamed Taliban militants for organizing the bloody attack. However, the outfit has yet to make comment. Since launching the Taliban's so-called spring offensive in April 28, militancy and violent incidents have gone up in the conflict-ridden Afghanistan. Paktika province is 155 kilometers south of Kabul, the national capital.
