Three civilians killed in bus bomb blast in Syrian city of Afrin

A bomb blast in a bus killed three civilians Sunday in the northern Syrian city of Afrin on the first anniversary of a Turkish attack on the Kurdish-majority region, a war monitor said. Nine other people, including fighters, were killed in the explosion, said the head of the Britain-based Syrian Observatory for Human Rights. Turkish troops and allied rebel groups seized the Afrin region from Kurdish forces in March last year after a two-month air and ground offensive.
