The blast occurred midday Sunday near the Sharqiya Governorate’s Military Intelligence Headquarters as a result of a car bomb, local media outlets report, citing the governorate’s authorities.

Moreover, Army Spokesman Ahmed Ali confirmed on his official Facebook page Sunday that four soldiers were wounded by the blast which partially destroyed the building's rear façade, Al-Ahram Arabic News Website reported.

Ali further condemned the terrorist attacks targeting Egypt's military and state facilities.

Meanwhile, a security official told state news agency MENA Egyptian security forces have arrested a suspect believed involved in the bomb blast.

Two other explosions also struck Egypt last week. On Tuesday, a huge bomb rocked the Security Directorate building in the Nile Delta city of Mansoura, killing 16 people and injuring more than 135, while on Thursday a smaller blast near a public bus in eastern Cairo's Nasr City injured five people.

Although a Sinai-based al-Qaeda-linked militant group, known Ansar Bait Al-Maqdis, has claimed responsibility for the Mansoura bombing, Egypt's interim government blames the Muslim Brotherhood for the attack.

This is while the Brotherhood has denies any involvement with the blast.

No group, however, has yet claimed responsibility for the Sunday blast which, according to explosives experts, was planted on the road rather than on a bus.

The explosives experts have also managed to defuse another bomb found near the Nasr City explosion site, which reportedly targeted security forces expected to rush to the scene following the blast.

The explosions have sparked nationwide panic. On Saturday, the discovery of a dummy bomb in Alexandria University caused panic on campus among students and professors.

Experts who examined the bomb found it to be devoid of explosive material.
