SASKATOON — Hassan Masri once cared for airstrike victims in Syria's civil war, but that didn't hardened him to the injuries he and other emergency staff at Saskatoon's Royal University Hospital saw Friday night after a horrific bus crash that killed 15 people.

The hospital declared a "code orange" meaning mass casualties are expected.

That designation means extra staff and extra machines are called in. Teams are organized to be assigned to each patient.

Everyone worked through the night treating 15 patients from a collision between a bus carrying the Humboldt Broncos junior hockey team and a transport truck in eastern Saskatchewan. One of those patients later died, the RCMP said Saturday.

But after hours and hours of working non-stop, Masri was able to look up and remember he's human.
