Police in Northern Ireland have arrested two men in connection with the fatal shooting of a journalist.
The unidentified 18-year-old and 19-year-old men were arrested in Londonderry Saturday under anti-terrorism laws. They have not been charged, but were taken to Belfast for questioning, the Police Service of Northern Ireland said.
Police say they believe that at least one of the gunmen may be connected with the New IRA, a republican paramilitary group that opposes the shift towards non-violent tactics to form a united Ireland.
Journalist Lyra McKee, who was 29, was shot in the head late Thursday during rioting in the Creggan district of Londonderry. McKee had posted photos on social media of the riots with text that read: 'Derry tonight, Absolute Madness.'
