Two Canadians—a doctor and a filmmaker—are being held in a jail in Egypt.

They have been there since Aug. 16.

Tarek Loubani and John Greyson have been told that they, along with about 600 others arrested in August, will be held for 45 more days.

On August 16, Loubani and Greyson witnessed a violent clash between Egyptian security forces and supporters of the country’s former president, Mohammed Morsi.

Dr. Loubani had travelled to Egypt to volunteer at a hospital. Greyson was there to make a short film about Loubani and his work.

When they saw the clash happen, they did what they do best: Dr. Loubani started treating the wounded and Greyson filmed the incident.
