A shootout between two rival Vietnamese gangs left six people dead and several wounded in a northern port city of the communist country early on Monday, state media reported.
The gunmen shot at each other in a high speed car and motorcycle chase in a harbour area of Halong City, 160 kilometres (100 miles) east of the capital Hanoi, the Lao Dong (Labour) newspaper said in an online report.
"The killings resulted from a conflict between two gangs in Ha Long City," the report said, adding that several wounded gunmen had escaped while police had blocked the area off for investigation.
Halong City police refused to comment when contacted by AFP.
Vietnam's northern ports of Halong City and nearby Haiphong located near the World heritage listed Halong Bay scenic island region are notorious for smuggling, prostitution, drug abuse and other vice.
