A 29-year-old woman has been shot dead in Londonderry.
Dissident Republicans are being blamed for the killing.
It happened during rioting following police searches in Derry’s Creggan area on Thursday night.
Petrol bombs were also thrown at police Land Rovers.
There are reports that the trouble broke out after police raids on houses in the Mulroy Park and Galliagh areas.
Assistant Chief Constable Mark Hamilton said the police were “treating the shooting as a terrorist incident” and a murder inquiry had been launched.
