It started with mortars. A series of whooshes from north and south followed seconds later by explosions inside the perimeter. Figures emerged from the gloom and knelt in the middle of Hi al-Elam and Qatar Nada streets, pointing rocket launchers.

More figures materialised on rooftops overlooking the station to spray gunfire and lob grenades. Dozens of gunmen, guerrilla infantry, swarmed from houses and alleys. It was just after 5.30am and the station was surrounded.
