The military said in a statement Sunday that another 49 suspected militants have been arrested.
It says it destroyed 26 hideouts and weapons depots, and dismantled 64 explosive devices.
The military says airstrikes destroyed 32 vehicles containing weapons and ammunition in the Western Desert and in the south.
It wasn’t possible to independently confirm the claims as access to the northern Sinai is heavily restricted.
Egypt launched a nationwide operation against militants in February.
