Flash flooding caused by torrential rains has killed eight people, including at least four children in northern Turkey, authorities said Wednesday. The downpours caused a river to burst its banks late Tuesday, inundating homes and shops and stranding cars in the Black Sea port city of Samsun, the state-run Anadolu agency reported Wednesday. The country's emergency management authority said at least eight people were killed and two others were missing in Samsun. It said 21 people were injured.
