As the capital began its first day of separating high-risk areas for coronavirus control, traffic congestion inundated several checkpoints.

At 7 a.m. on Monday, vehicles could be seen congesting a Covid-19 checkpoint on Cau Dien Street of Bac Tu Liem District.

Starting last Saturday, authorities erected checkpoints to separate high-risk areas in the capital.

Hanoi said high-risk areas include locations in Tay Ho, Ba Dinh, Cau Giay, Hoan Kiem, Dong Da, Hai Ba Trung, Thanh Xuan, Ha Dong, Thanh Tri, Hoang Mai, Nam Tu Liem, Bac Tu Liem, Hoai Duc, Thanh Oai and Thuong Tin.
