The ministry said in a statement on Wednesday night that police had received intelligence information that the group was planning to carry out "terrorist" attacks around the date of the second anniversary of the 30 June mass protests which led to the overthrow of former Islamist president Mohamed Morsi.
The officers shot the men after they opened fire on them while attempting to escape, Giza deputy security director Magdy Abd El-Aal had told told Ahram Arabic news website earlier in the evening.
The now-banned Muslim Brotherhood, which has been blamed by the government for orchestrating terrorist attacks against security forces in the last two years, denied that the men were armed.
