Northern Ireland protesters attack police

Crowds of youths in a pro-British area of Belfast have set a hijacked bus on fire and attacked police with stones in the latest of a series of nightly outbreaks of violence that began last week.

Dozens of police officers have been injured as a result of the nightly violence which has included the burning of cars and petrol-bomb attacks on police.

The violence comes amid growing frustration among many in the pro-British unionist community at new trade barriers between Northern Ireland and the rest of the United Kingdom that resulted from the country's exit from the European Union.

The pro-UK Democratic Unionist Party (DUP) have also pointed to a decision by police not to prosecute Irish nationalists Sinn Fein for a large funeral last year that broke COVID-19 regulations.

Sinn Fein in turn have blamed the DUP for stoking tensions with their staunch opposition to the new trading arrangements and their call in recent days for the region's police chief to step down.

The Police Service of Northern Ireland has said some of the violence was influenced by "criminal elements" who helped to orchestrate the attacks.

The violence on Wednesday took place near the Shankill Road in west Belfast near a so-called "peace wall" that divides the community from the Irish nationalist stronghold of the Falls Road, where groups of youths also gathered.

The walls and fences were built between the two communities to prevent clashes during three decades of sectarian violence in Northern Ireland that largely ended with a 1998 peace deal.

The leaders of Northern Ireland's largest political parties Sinn Fein and the DUP both condemned the violence, pointing in particular to the bus hijacking and an attack on a photojournalist from the Belfast Telegraph newspaper.

"These actions do not represent unionism or loyalism. They are an embarrassment to Northern Ireland," DUP leader Arlene Foster wrote in a Twitter post that went on to describe rivals Sinn Fein as "the real law breakers".
