At least two people were killed and six others were wounded in separate roadside bombings and a gunfire attack in Afghanistan on Thursday. A member of Afghan Intelligence agency named Taj Mohammad was killed in a drive-by shooting at around 5 p.m. local time in Shindand district in western Herat province, district police chief, Ghulam Sakhi Housaini, told Xinhua, adding the attacker fled the site shortly after the incident. Separately, a woman was killed and a child was wounded in a roadside bombing targeting a police unit also in Shindand in the province 640 km west of capital city of Kabul, Housanini said, adding no member of the police mobile was harmed in the attack. In addition, five policemen were wounded in a roadside bomb attack in Surkh Rod district in eastern Nangarhar province earlier Thursday, a police spokesman in the province 120 km east of Kabul told Xinhua. No group has claimed responsibility for the attacks so far. However, the Taliban militant group, who has been waging an insurgency since its regime was toppled by a U.S.-led invasion in late 2001, was often responsible for such attacks.
