Thirteen people have died after a motorised rickshaw packed with civilian passengers struck a roadside bomb in eastern Afghanistan.
The explosion happened in the Khoshamad district of eastern Paktika province, the interior ministry said, adding that women and children were among the dead.
In western Herat province on Tuesday night, a rocket hit a civilian house during a fight between insurgents and Nato forces in the area, government spokesman Shafiq Berozyan said. A child was killed and another 10 people were wounded, he said.
The latest incidents came after two deadly roadside bombings this weekend.
On Saturday, six civilians were killed when their minibus hit a bomb in southern Helmand province. On Sunday, a stationwagon carrying a family of nine people struck a bomb in northern Baghlan province, killing all of those on board.
A recent United Nations report said there were 2,412 conflict-related civilian casualties in the first 10 months of 2010. More than three-quarters were caused by militant activity, a 25% increase from the same period in 2009, the report said. At the same time, civilian casualties attributed to pro-government forces decreased.
