Two terrorist attacks in the Al-Masoura district of northern Rafah left four people dead on Saturday morning.
In the first attack, unidentified assailants assaulted the Al-Masoura security barrier and placed an explosive device in an armoured vehicle that exploded, killing one policeman and two army conscripts.
An ambulance transferred the three security personnel to hospital.
In the second attack, a citizen named Ramy Qasem from South Sinai was shot dead by unknown assailants while he was walking along the street in Al-Masoura district.
Qasem, who was shot in the neck and head, was transferred to Rafah Central Hospital.
It is unclear whether or not the two incidents are related, and no groups immediately claimed responsibility for the attacks.
Security forces are investigating the site of the incidents, while a manhunt has begun for the perpetrators.
On Tuesday last week, four army conscripts and four civilians were killed when a roadside bomb struck an armoured vehicle in front of Rafah General Hospital.
