In Northern Ireland, a masked group attacked a police vehicle with Molotov cocktails.
Before the visit of US President Joe Biden to Northern Ireland, tensions rose in the country.
In celebration of the 25th anniversary of the Belfast Agreement (Good Friday Agreement), a protest was held in the city of Londonderry by nationalists who were against the agreement.
During the protests, a group of masked police officers attacked the vehicle with Molotov cocktails.
Derry City & Strabane District Superintendent Nigel Goddard said: “What we saw in Creggan this afternoon was incredibly demoralizing. This is a senseless and reckless attack on our police officers who are in the area to fulfill our legal duties.”
Police announced that evidence was collected at the scene and that an investigation into the attack would be conducted under the 2000 Terrorism Act.
It was reported that there were no casualties or injuries in the attack.
Terror threat level raised in Northern Ireland
British Minister for Northern Ireland Chris Heaton-Harris announced that the terrorist threat level in Northern Ireland had been raised from “significant” to “serious”, where the probability of an attack is high, and stated that the decision was taken by MI5, the British domestic intelligence agency.
Heaton-Harris said: “MI5 has raised the Northern Ireland-related terrorism threat to Northern Ireland from ‘significant’ to ‘serious’. “The public should remain vigilant but not panic and continue to raise their concerns to the Police Service of Northern Ireland (PSNI),” he said.
Biden will arrive in the capital Belfast and visit Ireland on Wednesday.
