Dubliners are voicing their disgust as a march led by republican group Saoradh makes its way down O'Connell Street.

Gardai are understood to be at the scene of the demonstration by the hardliners, with hundreds of people reportedly taking part.

Men dressed in military fatigues wearing dark glasses and berets marched in rows of three down the city's main thoroughfare in a show of strength - less than 48 hours after a young journalist was murdered by dissidents in Derry.

The group had announced that they would be meeting at the Garden of Remembrance at 3pm today.

Just yesterday, Saoradh released a statement claiming that a 'Republican Volunteer' was attempting to 'defend people' from the 'PSNI/RUC' when Lyra McKee was murdered in Derry on Thursday night.

Ms McKee, 29, was shot in the head and died in hospital after being rushed from the scene in a police Land Rover.

Two people have since been arrested in connection with the killing.

A garda spokesman said: "A peaceful demonstration is currently underway at O’Connell St in Dublin. No incidents have been reported. Gardaí are at scene."
