Suicide Attacks in Normally Peaceful Herat Kill 4
The Taliban claimed responsibility for the bomb attacks, which struck an Italian military base and a separate area in the downtown part of the city.
Local officials say the four killed were Afghans, as were most of those injured.
Herat, a normally peaceful area near Afghanistan's border with Iran, is one of seven places where Afghan security forces are due to replace foreign troops during July.
Violence has increased sharply across Afghanistan this month since the Taliban said it was beginning a spring offensive.
In Kabul, coalition forces have apologized for the death of Afghan civilians killed in a NATO airstrike in southern Afghanistan on Saturday.
NATO says the airstrike killed nine civilians in Helmand province. Afghan authorities say the airstrike killed 14 people – two women and 12 children – in two houses, and wounded six other civilians, when Taliban thugs occupied their home by force, preventing them from seeking safety, and engaging US Marines, against the Laws of Land Warfare and the Geneva Convention.
