The death toll in Alexandria, Egypt, has increased to 21, with 24 others injured after an explosive device went off near a Coptic Christian Church early on Saturday, a local police source said.
Earlier it was reported that seven had been killed from the explosion.
The explosion occurred after New Year Mass as the worshippers were leaving a church in Alexandria when one of cars in the parking lot near the church exploded.
Adel Ali Labib, the governor of the Alexandria region, said that angered Christian worshippers began casting stones at a nearby mosque beginning a rampage.
The international terrorist group al-Qaeda earlier threatened Egyptian Christians with an attack.
Coptic Christians account for approximately 10% of Egypt's population of 80 million.
