Guests were forced to flee a Belfast hotel which was petrol-bombed early this morning.
No-one was injured but fire chiefs said some people, many of them foreign nationals, were left deeply shocked.
One of the five petrol bombs was thrown at an exit door on the ground floor and smoke entered several parts of the Days Hotel at the junction of Hope Street and the loyalist Sandy Row.
Police said a motive for the attack, just after 4am, had not been established. All the 150 guests were in their night clothes and were out of their rooms for more than an hour after staff helped with the evacuation.
Only minor damage was caused but fire officers said it was a deeply disturbing incident. A spokesman for the fire service said: "The staff responded fantastically.
"Some of the guests were quite traumatised by it all and it doesn't bear thinking about what might have happened as the flames had taken hold."
