Canadian Prime Minister Justin Trudeau has condemned the "cold-blooded murder" of a Canadian by terrorists in the Philippines who were holding him hostage.

Trudeau confirmed Monday that the victim was John Ridsdel of Calgary, Alberta. He was 68 years old.

Ridsdel was one of four tourists — including Canadian Robert Hall, a Norwegian man and a Filipino woman — that were kidnapped last September by Abu Sayyaf militants from a marina on southern Samal Island.

The militants had threatened to kill one of the three male hostages if a large ransom was not paid by 3 p.m. Monday local time — 0800 GMT.

Trudeau says his government will work with the government of the Philippines and international partners to pursue those responsible for this "heinous act."
