HANOI, July 30 (CGTN) -- Fourteen members of the same family were killed in a car crash in central Vietnam on Monday en route to a wedding party, including the groom, who died instantly when their van hit a container truck, police said.

The victims of Monday's car crash in Quang Nam were members of an extended family who were heading to the bride's family home in a neighboring province, a police officer said.

Their 16-seater van collided with a container truck at around 2.30 am local time, killing 13 people instantly. Another died later in hospital.

"All victims' bodies were brought back to their home for burial. We are treating some of the injured in a local hospital," said the policeman, who requested anonymity.

Local authorities said Monday they were investigating the cause of the deadly crash.

Road accidents are the leading cause of death in Vietnam, where traffic laws are loosely obeyed and road infrastructure is patchy.

Around 8,200 people died in traffic accidents across Vietnam last year, down from about 8,600 the year before. Most of those killed were on motorbikes.
