A bomb-laden car exploded in North Sinai after security forces shot at it in suspicion, a security source told Ahram Arabic website.
The car, according to the source, was heading in the direction of Al-Zohour military camp near the city of Sheikh Zuwaid. The driver escaped before the car exploded. No injuries were reported.
This was the second car bomb incident in Sinai in less than a month. On 20 November, a bomb-laden car drove into an army convoy carrying off-duty soldiers killing 11 and injuring 37.
The army spokesman, Colonel Ahmed Ali, released a statement on Sunday evening saying that around the same time, a special unit of the security forces en route to its camp and encountered another suspicious-looking car on the roadside. The unit fired at the vehicle and it exploded as well. Initial inspection, according to the spokesman, revealed that car was laden with explosives.
The restive peninsula, already suffering a security vacuum since the ouster of autocrat Hosni Mubarak in 2011, has seen a spike in militant activity since Mohamed Morsi's ouster in July 2013.
Attacks on security and army targets in the Sinai region have killed over 100 since July.
Dozens of militants have been killed since the army began a campaign to flush out "terrorists" and seize or destroy arms caches in the Sinai region.
