Taliban fighters have killed at least 14 members of a pro-government militia in Afghanistan, officials said, as the group aims to reach a deal with the United States to end the 18-year war.

Government officials said on Wednesday that several civilians were wounded in the clashes in the western province of Herat.

Abdul Ahad Walizada, a spokesman for the Herat police, said the men were killed in Rubat-e-Sangi district of Herat after a large number of Taliban fighters stormed security checkpoints in the Chahardara area.
