Four terrorists were killed on Friday in a fire exchange with police in Kerdasa district near the capital, the interior ministry said in a statement, APA reports quoting Xinhua.
One of the dead was Sameh Farahat, a prominent figure in a terrorist cell, said the statement.
Farahat along with other militants have been meeting in an apartment in Kerdasa for preparing and planning for a massive attack in the coming period, according to confirmed information, added the interior ministry.
The forces seized large amount of guns and ammunition in the raid, it added.
Kerdasa, located in Giza province, south-west Cairo, is one of the main strongholds for the supporters of the outlawed Muslim Brotherhood group and Islamists.
Egypt has been battling waves of terrorist attacks that were centered mainly in North Sinai, since the army-led ouster of Brotherhood's president Mohamed Morsi in 2013, in response to nation-wide protests against his rule. However, some of the attacks have extended to Cairo and other cities.
