A video has emerged of two Canadians who are being held hostage by Abu Sayyaf gunmen in the Philippines, appealing to the Canadian government to pay their ransom.

Canadians John Ridsdel and Robert Hall warn they will be beheaded if their ransom is not paid within the next 10 days.

The two men are among four hostages who speak directly to the camera in the troubling video.

“This is a final, urgent appeal to governments -- Philippine, Canadian – and families,” Ridsdel says in the video. “If $300 million (Philippine pesos) is not paid for me by 3 p.m. on April 25, they will behead me.”

In the video, Hull said he is appealing specifically to the Canadian government, “who I know has the capacity to get us out of here. I’m wondering what they’re waiting for.”

In September, gunmen abducted Ridsdel and Hall, along with Norwegian Kjartan Sekkingstad and Filipino Marites Flor, at an upscale resort complex on a southern Philippine island.

In a video released late last year, the militants demanded more than $60 million for the release of the four hostages.
