Two separate roadside blasts in southern Afghanistan killed 14 civilians, including three children, underscoring the high price paid by ordinary people in the conflict with the Taliban, officials said Thursday.

Officials blamed the blasts on Taliban militants, who have made roadside bombings their primary weapons.

According to figures from the U.S.-based Joint Improvised Explosive Device Defeat Organization, the number of incidents from IEDs soared to 828 last month, the highest level of the war and more than twice as many as in July 2008. The majority of the victims in such attacks have been civilians.

A blast on a road in the Gereshk district of Helmand province ripped through a vehicle carrying a family on Wednesday, killing 11 people, including two women and nine men, said Daud Ahmadi, the spokesman for the provincial governor.

A 6-year-old girl survived the bombing, Ahmadi said.

"The Taliban are planting these bombs on the main roads, which are killing our civilians," Ahmadi said.
