At least 24 Egyptian policemen were killed and two injured in an attack Monday morning in the northern Sinai Peninsula, security and medical sources said.
According to the sources, two personnel carriers came under attack by unidentified militants firing rocket-propelled grenades near the Abu Tawila area on the Rafah international road.
No official statement has been issued by the authorities regarding the attack.
The incident is the deadliest of its kind since August of last year, when 16 Egyptian border guards were killed as they broke their Ramadan fast in an attack by unidentified gunmen at a border checkpoint near the North Sinai city of Rafah.
Egypt's Sinai Peninsula, which shares borders with both Israel and the Palestinian Gaza Strip, has seen almost daily attacks by unknown assailants since ousted president Mohamed Morsi's July 3 overthrow by the military.
