KABUL, Jan. 15 (Xinhua) -- Eight Afghan civilians, including seven children, were killed following a U.S. force's airstrike in eastern province of Parwan on Tuesday night, said a statement issued by the country's Presidential Palace late on Wednesday.
"Afghan President Hamid Karzai condemned in strongest terms a bombardment carried out by the U.S. forces in Siya Gard District of Parwan Province, which led to the deaths of one woman and seven children," the statement said.
One civilian was also wounded in the attack which took place in Sah Darah-e-Wazghar area of the district in the province, it noted.
"The Afghan government for many years, had demanded a complete end to the military operations in Afghan villages and towns," the statement said, adding against all bilateral agreements and the recent guarantee in a letter by the U.S. President Barack Obama, the American forces once again carried out the airstrike against residential area and caused civilian casualties.
The deaths of Afghan civilians by NATO-led troops during operations against Taliban have long been a contentious issue between the Afghan government and U.S. and NATO forces in the insurgency-hit country.
Afghan officials had stressed in the past that such deaths would further undermine the war against Taliban and terrorist groups and inflame an anti-foreign sentiment in the country.
The Afghan leader, under strain from Afghan public, has long been criticizing the NATO and U.S. forces over their erroneous killing of civilians since the war against terror begun in late 2001.
The statement also said that an investigation team has been sent to Siya Gard district and they must bring back the result of the probe within three days to the president of Afghanistan.
