FARAH, Afghanistan, Sept. 9 (Xinhua) -- One civilian was killed and 12 people were injured in three successive explosions in Farah city, the provincial capital of western Afghanistan's Farah province on Sunday, an official said.
"The explosive were placed in three different places near the provincial government office building and the first explosion was a motorbike blast that occurred at around 11:30 a.m. local time, leaving the casualties," a provincial government spokesman Abdul Rahman Zhwandi told Xinhua.
The injured included six Afghan policemen, he said.
Police and the rescue team reached the site following the attacks were reported and all the injured were rushed to nearby hospitals.
No one has so far claimed credit for the attacks, though the bombings bear the hallmark of Taliban insurgent group.
In an unrelated incident, seven militants, who were placing roadside bombs or Improvised Explosive Devices (IEDs) along a main road in Miyanshin district of southern Kandahar province, were killed in an airstrike over night, the provincial government said in a statement on Sunday.
"The militants were killed in an airstrike carried out by the NATO-led coalition forces and during a post-strike assessment operation an AK-47 and 10 IEDs were found at the scene," the statement said.
The Taliban insurgents, who have been waging more than a decade- long insurgency, launched an annual spring offensive starting from May 3 to target Afghan forces as well as U.S. and NATO troops across the country.
The insurgent group has warned the civilians to stay away from official gatherings, military convoys and centers regarded as the legitimate targets by militants.
