2 teenagers arrested in fatal shooting of journalist in Northern Ireland

LONDON — Police in Northern Ireland arrested two teenagers Saturday in connection with the fatal shooting of a journalist during rioting in the city of Londonderry.

The men, aged 18 and 19, were detained under anti-terrorism legislation and taken to Belfast for questioning, the Police Service of Northern Ireland said.

The men have not been identified or charged. Police had said earlier there was one gunman who pulled the trigger who had been backed by an “organization” and that they are searching for more suspects.

Lyra McKee, 29, a rising star of investigative journalism, was shot and killed, probably by a stray bullet aimed at police, during rioting Thursday night. Police said the New IRA dissident group was most likely responsible and called it a “terrorist act.”

The use of a firearm apparently aimed at police marks a dangerous escalation in sporadic violence that continues to plague Northern Ireland 21 years after the Good Friday peace agreement was signed.

Assistant Chief Constable Mark Hamilton said earlier that a gunman fired a number of shots at police during the unrest. Police released video footage Friday night showing the man suspected of firing the shots that killed McKee.

The footage shows the police facing a barrage of gasoline bombs before the shots were fired by someone wearing a balaclava to obscure his face.

Police appealed for help from the community, stating that people knew the shooter and should help police identify him. The rioting started after police moved into the Creggan housing complex to search for weapons.

The killing was condemned by all the major political parties as well as the prime ministers of Britain and Ireland.
