Four people were killed and 11 others got injured when a knife-wielding man suddenly attacked passengers in a bus in China's Sichuan province Sunday night, police said.
The bus camera shows that the man suddenly took out a knife and started to stab the passengers on the bus running through Sichuan's capital Chengdu, about 1,850 km from here, Xinhua reported citing the city's public security office.
The man, surnamed Li, got off the bus soon and continued attacking the people in the street before police opened fire and subdued him.
