2005 Sharm El Sheikh bombings
The 2005 Sharm El Sheikh bombings were committed by Islamist group Abdullah Azzam Brigades on 23 July 2005 in the Egyptian resort city of Sharm El Sheikh, at the southern tip of the Sinai Peninsula. Eighty-eight people were killed by the three bombings, the majority of them Egyptians, and over 200 were injured, making the attack the deadliest terrorist action in the history of Egypt, until it was surpassed by the 2017 Sinai mosque attack.
