Two arrested over Lyra McKee murder

Two teenagers have been arrested by police in connection with the murder of journalist Lyra McKee in Northern Ireland.

The men, aged 18 and 19, were detained under anti-terrorism legislation and have been taken to a police station in Belfast for questioning, the Police Service of Northern Ireland (PSNI) said.

An outpouring of tributes to the 29-year-old was led by her partner, Sara Canning, who said Ms McKee's "amazing potential was snuffed out by this single barbaric act".

Detectives hunting the gunman have released footage of the shooting in the hope the community can help trace her killers.

The published author, from Belfast, was shot in the head by suspects who police believe were dissident republicans linked to the New IRA, as they clashed with police on the Creggan estate in Londonderry on Thursday night.
