Egyptian security forces killed a terrorist from the Hasm group, which is affiliated with the terrorist-designated Muslim Brotherhood organisation, during a security raid against a hideout in Al-Matareya district in East Cairo, a Ministry of Interior statement said late Saturday.
"The terrorist hideout was used as a weapons warehouse in preparation to be used in hostile attacks to disrupt the country's security and stability," the statement said.
The statement added that two National Security officers were injured after the terrorist group opened fire as security forces approached.
Security forces seized large amounts of firearms, ammunition, explosives, bombs, electric circuits, as well as a number of RPG launchers and projectiles.
Egypt designated the Muslim Brotherhood a terrorist group in late 2013.
