A total of six people were injured Tuesday morning when two successive blasts rocked Jalalabad city, the provincial capital of eastern Afghanistan's Nangarhar province, said the country's Interior Ministry.

"Initially, there was a mine explosion in front of a shop in the first precinct of Jalalabad city at around 6:00 a.m. local time, with no casualties, but shortly after a unit of police arrived in the scene another bomb went off, injuring six people," the ministry said in a press release.

It said the injured include two policemen, two mine clearance personnel, a child and a member of Afghan National Directorate of Security or intelligence agency.

The press release also said that the injured were shifted to a provincial capital hospital and that none of the injuries was life- threatening.

The back-to-back blasts also damaged several shops around the scene besides shattering the windowpanes of a number of buildings nearby.

No group has claimed responsibility for the incident in the city, some 120 km east of capital city of Kabul, so far.

The Taliban-led insurgency has been rampant since the militant group launched a rebel offensive from May, 2011 against Afghan and NATO-led troops stationed in Afghanistan.

Three civilians were killed and another injured in a suicide bombing on a police checkpoint in neighboring Khost province on Sunday.

The Taliban has warned the civilians to stay away from official gatherings, military convoys and centers regarded as the legitimate targets by militants besides warning people against supporting government and foreign troops.
