CAIRO, Jul 24 (Aswat Masriya) - An explosion in North Sinai's Sheikh Zuweid town injured two military officers and a conscript late Friday, security sources said.

Security forces were combing an area in the village of Goora when the explosion occurred, sources said. The three injured military personnel were transferred to hospital for treatment.

Earlier on Friday, the armed forces spokesman announced that security forces killed 12 "terrorists" in North Sinai.

Egypt has been battling a wave of militancy since the military ouster of Islamist President Mohamed Mursi in July 2013, after mass protests against his rule. The majority of attacks target security forces.

The Sinai-based Ansar Bayt al-Maqdis has claimed responsibility for the majority of attacks carried out in Sinai since mid-2013. The militant group changed its name to 'Sinai Province' last November, after pledging allegiance to Islamic State fighters in Syria and Iraq.

The militant group claimed responsibility for a bomb attack which claimed the lives of four military personnel on Thursday.
