A 29-year-old woman was shot dead in the Creggan area of Derry last night.
She was hit in the head by one of four shots fired by a masked gunman in the Fanad Drive area.
The woman was among onlookers in an area where there was a hijacking and burning of a van and a car.
She has been named as Lyra McKee (pictured above), a freelance journalist from the Ardoyne area of Belfast.
She was rushed to Altnagelvin Hospital in a police land rover but was pronounced dead a short time later.
The trouble broke out as police were carrying out a search of a house in the nearby Mulroy Gardens area.
This morning the PSNI released a statement condemning the "terrorist incident", and confirmed a murder investigation was launched.
Assistant Chief Constable for District Policing, Mark Hamilton appealed for no further violence over the Easter weekend.
He said: “Lyra McKee was murdered during orchestrated violence in Creggan last night."
ACC Mark Hamilton says ‘our thoughts are very much with the family & friends of Lyra McKee’. He says her murder ‘demonstrates all too starkly when terrorists bring violence & guns into the community members of the public are placed in severe danger’. pic.twitter.com/26TJZMkLGD
