There are sharks in the Red Sea, but encounters with them are relatively rare.
The ministry said the attack occurred in deep water outside the designated swimming zone near the jetties in northern Marsa Alam, adding that swimming out from the jetties was prohibited and the jetties would be closed for two days from Dec 30.
Marsa Alam is an Egyptian coastal town known for its coral reefs, marine life and beaches.
The last similar incident was in June 2023 when a tiger shark killed a Russian in Hurghada, another coastal city on the Red Sea north of Marsa Alam.
In November, a tourist boat capsized in the same area, leaving four dead and seven missing.
