A roadside bombing in Egypt's restive Sinai Peninsula killed two policemen on Monday, the interior ministry announced, in the latest in a string of attacks on security forces.

The bomb exploded close to an armoured vehicle on a highway near El-Arish, the provincial capital of North Sinai, it said in a statement.

Militants have killed hundreds of soldiers and policemen in attacks in the peninsula.

On Sunday, gunmen killed two members of the security forces in an ambulance as they were being taken to hospital with injuries from a bombing. A medic was also shot dead.

Most of the Sinai attacks are claimed by the so-called 'Islamic State of Iraq and the Levant' takfiri group's Egyptian branch, "Sinai Province".

ISIL also said it carried out the bombing in October of a Russian airliner over Sinai, killing all 224 people on board.

Sinai militants pledged allegiance in November 2014 to IS, which occupies parts of Iraq and Syria and also has a presence in conflict-ridden Libya.

Armed groups, who have long used Sinai as a base, launched an insurgency after the military overthrew Egypt's Muslim Brotherhood president Mohammad Mursi in 2013.
