In extensive security operations to end terrorist activities in Sinai, Egypt's army and police forces have successfully arrested 23 militants, killing 11 and injuring one, a military source said on Wednesday.

Army and police forces launched widespread security campaigns following the recent Rafah attack that resulted in the death of 16 Egyptian army and police men.

The source added that forces were also able to confiscate 11 loaded carriages carrying arms including machine guns and bombs, reported the Middle East News Agency.

Security operations will continue until the area is clear from criminal activities, the source insisted, adding that starting Wednesday morning the operations will be expanded.
