Police in Northern Ireland said Friday they are searching for multiple suspects in the fatal shooting of a journalist during overnight rioting in the city of Londonderry.
"A senseless act. A family has been torn apart".
"The loss of such a journalistic talent is vast, but the loss of such a genuinely lovely, warm and empathic person is a huge and enduring heartbreak for her family and partner and my thoughts are with them all".
The North's Policing Board said it was "utterly shocking that a young woman has been killed tonight in Derry/Londonderry".
"She was a journalist who died doing her job with great courage", May said. It is abundantly clear that they do not care who they harm.
"A single gunman fired shots in a residential area of the city and as a result wounded Ms McKee". The New IRA, an amalgamation of dissident republican factions in Derry, has been blamed for a bombing in Bishop Street, Derry, in January.
Lyra McKee was an editor for the news site Mediagazer, and her work appeared in Buzzfeed and The Atlantic.
"I knew Lyra McKee very well - I was one of her media lecturers as part of the Headliners project some years ago and we have been in regular contact since then". Ireland's Prime Minister Leo Varadkar warned that "we can not allow those who want to propagate violence, fear and hate to drag us back to the past".
The Conservative Mid Norfolk MP posted on Twitter to say that it was "heartbreaking" to hear of Lyra McKee's murder in Derry on Thursday, before adding: "We can not allow a Brexit which undermines the peace in N Ireland".
"We condemn such violence, and we are confident that the United Kingdom authorities will ascertain the exact circumstances of this tragic event", he said.
Matthew Hughes tweeted: "She was one of my closest friends".
Catholic priest Father Joseph Gormley comforted Ms McKee's family in hospital and accused the killers of forcing their viewpoint on others using the barrel of a gun.
"Have you no sense of humanity or dignity about yourself?" McKee doggedly pursued a line that at least one of the IRA figures associated with the murder plot may have been a Special Branch informer at the time of the Bradford assassination.
"This can not stand. Lyra's death must not be in vain because her life was a shining light in everyone else's life".
There has been an uptick in violence in Northern Ireland amid heightened fears that sectarian violence might be revived over concerns about the effects of Brexit.
"We stand here today to mark Lyra's memory in the best way that we can, and that is to dedicate ourselves to peace", she said.
U.S. Speaker of the House Nancy Pelosi, who is visiting the region, joined in a minute of silence for McKee, calling the fact that it came on Good Friday "especially poignant".
'Supt Alan Hutton said: 'We are now responding to reports that a member of the public has been injured and I would appeal for calm'.
