Egypt says it has renewed for another year its "combat" military deployment in the Red Sea and Persian Gulf regions.

The Thursday's statement, like similar past ones, does not specify the number of troops or military assets Egypt is deploying in the two strategic regions.

Egypt is known to have deployed warships in the Red Sea near its southern entrance, Bab al-Mandab, as part of a Saudi-led alliance fighting Iranian-backed Shiite rebels and supporters of a former president in Yemen. The alliance began a campaign of airstrikes in Yemen in March last year.

Troops from several members of the alliance are fighting the rebels, known as Houthis, and their allies on the ground in parts of Yemen alongside forces loyal to the internationally recognized government and its allies.
