An Egypt Air flight from Alexandria’s Burg Al-Arab airport to Cairo was hijacked to Cyprus on Tuesday.

Egypt Air flight MS 181 was scheduled to land in the capital at 7:15 a.m. One hijacker told the pilot that he was wearing an explosive belt, Al Arabiya television reported, without saying how it obtained the information.

Militant attacks in Egypt have surged since 2013, hampering the country’s efforts to revive its economy and lure in foreign investors. A Russian passenger plane was brought down over Sinai in October in an attack claimed by the Islamic State group.

Global airline and airport security officials are on heightened alert after bombs ripped through the airport in Belgium’s capital Brussels last week. Asian airports had stepped up checks since the Paris terrorist attacks and the suspected bombing of the Russian aircraft over Sinai.
