An unmarked police car has been attacked by a masked gang of 15 men in east Belfast, then burnt out opposite Alliance Party MP Naomi Long's office.

The windows were smashed and a petrol bomb thrown in while an officer was still inside. He was not injured.

It happened on the Upper Newtownards Road at about 19:35 GMT. Police have said they are treating the attack as attempted murder.

There has also been rioting in the loyalist Village area of south Belfast.

Mark Simpson reports.
