The major anti-terror offensive in the area started on February 9.
According to the statement the army has also destroyed several explosive devices, weapon depots, terrorist hideouts and an underground storage of fuel.
A convoy of 11 cars loaded with weapons trying to trespass the Libyan-Egyptian border has been eliminated, the statement read further.
Cairo has been engaging in anti-terror activities on the Sinai Peninsula for years, where militants have repeatedly staged deadly attacks. In 2014, a state of emergency was introduced on the peninsula after militants attacked Egyptian security officers in the area.
In late December, Egypt’s President Abdel Fattah Sisi ordered the country’s armed forces to end militant activities on the peninsula within three months.
