Parts of Northern Ireland saw their sixth consecutive night of violence Wednesday as unionists and nationalists clashed with police and each other.
Unrest first broke out last week amid rising tensions relating to Brexit and unionist anger over a decision by police not to prosecute leaders of the Irish nationalist party Sinn Fein for allegedly breaking coronavirus restrictions during the funeral of a former leading IRA figure.
In west Belfast on Wednesday, rioters clashed along the so-called "peace line" dividing predominantly unionist and nationalist communities, with police struggling to close a gate designed to separate the areas.
A bus was set on fire on Lanark Way near the junction with Shankill Road, police said. Photos and video from the scene showed youths on both sides of the gate throwing projectiles across, including petrol bombs.
In a statement, Irish Taoiseach Micheal Martin condemned the violence and "attacks on police," adding the "only way forward is to address issues of concern through peaceful and democratic means."
"Now is the time for the two Governments and leaders on all sides to work together to defuse tensions and restore calm," Martin said.
British Prime Minister Boris Johnson said he was "deeply concerned by the scenes of violence" in Northern Ireland.
"The way to resolve differences is through dialogue, not violence or criminality," Johnson said on Twitter.
