Three people are dead, including two boys aged 10 and 13, after the van they were travelling in collided with a semi on the Trans-Canada Highway near Portage la Prairie, Man. on Saturday afternoon.
The van, which was heading eastbound, collided with the semi while attempting to make a left turn to proceed north on Highway 16.
A 35-year-old male passenger and a 13-year-old boy were pronounced dead at the scene, while a 10-year-old boy died after being transported to hospital, the RCMP said.
