Malaysian Prime Minister Najib Razak said Islamic State is a "very real" threat to the country, hours after a video claiming to be from the regional wing of IS warned of attacks in the Muslim-majority nation for arresting its supporters.
Police said the video, believed to feature operatives from the militant group Katibah Nusantara speaking under the IS logo, was significant because, if confirmed, it was the first from Islamic State in Malay.
