A Canadian man working with the United Nations in the Syrian Golan Heights has disappeared, according to Israeli media reports.

The UN has confirmed that one of its staffers went missing along the Syrian-Israeli border, but would not disclose the person’s name or nationality.

The Times of Israel newspaper, however, reported that the missing man is Canadian citizen Carl Campeau, a civilian who was working as a legal adviser with the UN peacekeeping mission in the area.

According to the Times, Campeau was stationed at the United Nations Disengagement Observer Force base on the Syrian side of the demilitarized zone separating Israel and Syria.

It is believed that Syrian government troops have abandoned the area, leaving the rebels in control there.

Canada’s Department of Foreign Affairs has not commented on the disappearance, but government sources told The Canadian Press that a team has been assembled to investigate the situation. 

Canada participated in the peacekeeping mission along the Syrian border from 1974 until 2006, when the last remaining troops were withdrawn.
