A police officer in north Sinai was killed by armed assailants on Sunday, Egyptian state television reported.
The incident took place near a police station in Al-Arish city.
Violent attacks on security checkpoints and facilities in the peninsula have become frequent since the ouster of former president Mohamed Morsi in July.
Since July, daily attacks in north Sinai and other parts of the country by suspected militants have killed more than a hundred policemen.
In recent weeks, the Egyptian army has been carrying out an air and ground assault on Islamist militants in the sparsely populated peninsula, which borders Israel and the Palestinian Gaza Strip.
