CAIRO, Sept 23 (Reuters) - Egypt's President Abdel Fattah al-Sisi pardoned 100 prisoners including three Al Jazeera television journalists on Wednesday, a day before he plans to head to the annual United Nations summit of world leaders.

Canadian Mohamed Fahmy, Egyptian Baher Mohamed and Australian Peter Greste were sentenced to three years in prison in a retrial last month for operating without a press license and broadcasting material harmful to Egypt. Greste had already been deported in February.

A spokesperson for the Canadian government said that Canada was pleased with the pardon and it would help arrange Fahmy's departure from Egypt.
