Philippine forces are reportedly moving to rescue three remaining abductees after a Canadian was killed by his captors Sunday.
The military and police say they are putting out “maximum efforts” to find the trio.
The severed head of former mining executive John Ridsdel of Calgary was found in the Philippines’ Sulu province — a killing Prime Minister Justin Trudeau has condemned as a “cold-blooded murder.”
Interim Conservative leader Rona Ambrose called news of Ridsdel’s execution “shocking and saddening.”
N-D-P leader Tom Mulcair called on the Trudeau government to do everything possible to rescue the other hostages.
Ridsdel was one of four tourists, including fellow Canadian Robert Hall, who were kidnapped from a marina hotel in September by Abu Sayyaf militants.
He is being remembered as someone who built bridges between people and communities.
Ridsdel grew up in Yorkton, Saskatchewan.
