The military operation against the Wilayat Sinai (Sinai Province) militant group involved attack helicopters, planes and ground forces units, the Egyptian Masrawy news portal reported Monday.
Last week, Egypt's Air Force aircraft attacked a group of the Sinai Province militants and killed at least 40 terrorists.
The group notorious mostly for targeting military and security forces in the region. Recently, the group has also expanded its operations outside Sinai, notably in Egypt's Western Desert, relatively popular among tourists.
Egypt has been conducting anti-terrorist operations in North Sinai for the last two years, particularly against the Sinai Province previously known as Ansar Bait al-Maqdis.
