Egypt's interior ministry said in a statement that nine terrorists were killed during a Sunday morning raid on a farm in the Nile Delta's Sharqiya governorate.
The ministry said that the terrorists fired shots at police as they attempted to conduct the raid, leading to a shootout where the terrorists were killed.
The statement said that the terrorists were using the farm as a training camp to carry out terrorist operations in North Sinai.
Police seized seven machineguns as well as ammunition at the site.
The ministry also said that police raided another terrorist hideout in Cairo, arresting nine suspects and confiscating explosives and ammunition.
Four of those arrested were involved in an attack on a Cairo security checkpoint in July, which injured one conscript and one civilian, according to the ministry.
Police say both the Cairo and Sharqiya groups had links to the banned Muslim Brotherhood, from which they received financial support to carry out their operations.
The ministry said that the terrorists were planning to carry out attacks against several vital institutions.
Throughout the past months, Egypt's security forces have carried out raids on terrorist hideouts in multiple governorates, mainly killing or arresting members of the terrorist group Hasm, which authorities say is linked to the Muslim Brotherhood.
