Riots erupted last week in Belfast, Northern Ireland between nationalists, loyalists and the police over the Northern Ireland Protocol, a post-Brexit trading arrangement which they claim has created barriers between Northern Ireland and the rest of Britain. And pro-British demonstrators also protest a decision by police not to prosecute leaders of the Sinn Fein for allegedly breaking coronavirus restrictions during the funeral of a former leading Irish Republican Army (IRA) member. At least 55 police officers have been injured in clashes over the past six days.
