Two teenagers have been arrested in connection with the killing of journalist Lyra McKee.
The men, aged 18 and 19, were arrested under the Terrorism Act.
Ms McKee, 29, was struck by a bullet as she was observing rioting in Northern Ireland on Thursday night.
She was shot in Londonderry’s Creggan estate.
The Police Service of Northern Ireland (PSNI) said a gunman fired shots towards police officers at about 23:00 BST on Thursday.
Ms McKee was standing near a police 4×4 vehicle when she was wounded.
CCTV captured her final moments in the crowd and mobile phone footage showed the suspected gunman.
In the video, the masked attacker leans from behind cover and appears to fire shots towards police and onlookers.
