Afghan forces fought for hours against Taliban insurgents who killed at least four civilians and wounded dozens more when they stormed an aid organization in Kabul on Wednesday, security officials said.

The assault began shortly before midday, when a car bomb exploded in the compound of the nonprofit Counterpart International, in the Shahr Naw area of Kabul, the latest assault by Taliban insurgents even as they hold peace talks.

At least four civilians, including a woman and a policeman, were killed and 24 civilians and policemen were wounded, said Nasrat Rahimi, an interior ministry spokesman. One of the wounded was a foreign national, he said, but did not give his nationality.
