Police hunt for Syrian after explosives found in flat

German police stepped up security at airports and train stations on Sunday as they pressed a nationwide manhunt for a Syrian man suspected of plotting a bomb attack.

The suspect, Jaber Albakr, 22, has been on the run since police commandos stormed his flat on Saturday and found explosives which a bomb disposal squad later detonated in a controlled blast.

Police said the man, pictured wearing a black hooded sweatshirt, was "suspected of preparing a bomb attack", adding on Sunday that they were following more than 80 possible leads.
