An unknown armed group fired at the Central Security Forces camp in the
Ahrash district in Rafah, North Sinai on Sunday.

According to the Ahram Arabic news website, the attackers fled when the
police fired back. However, no casualties were reported.

The attackers were reportedly masked and drove a van equipped with
machine-guns on its roof.

The Sinai Peninsula, a largely desert area bordering Israel, has been the
site of several attacks by unknown assailants.

On 3 November three policemen were killed and three injured near the
Egypt-Israel border.

A few days later, on 6 November, a senior officer from the Ministry of
Interior's General Security was seriously injured after receiving two
bullets, one in his jaw and another in his left arm, from an attack by
unknown assailants.
