Egyptian authorities have finally given some indication of why they’ve been holding two Canadians since mid-August.

The Egyptian Foreign Ministry says a search of the hotel room of John Greyson and Tarek Loubani revealed video recordings and photos of the violent clashes that took place after President Mohammed Morsi was forced from office. They also claim to have found surveillance drones.

The allegations come as Foreign Affairs Minister John Baird warned the Egyptian government about worsening diplomatic relations if they continued to hold the two men without charging them.

A colleague of Loubani says the drones were actually toy helicopters being tested for transporting medical supplies in emergencies at the al Shifa hospital in Gaza, which is described as comprising several buildings surrounded by rugged terrain. Loubani and Greyson were on their way to the hospital when they were detained.

Meanwhile, the two men have ended a two-week hunger strike after they were given more chance to exercise while in jail.
