Ireland's ambassador to Germany has expressed "concern" to local authorities over a violent incident that saw an Irish demonstrator hit in the face by an officer at a pro-Palestinian rally in Berlin, the Foreign Ministry confirmed to dpa on Sunday, reported dpa. "The Department of Foreign Affairs and Trade is aware of the incident in question," it said in a statement. "The Ambassador in Berlin and senior officials in the Department have conveyed our concern about the incident to the German authorities." Videos of Thursday's protest show a police officer punching a protester twice in the face, leading to blood streaming from their nose. Irish Bloc Berlin, an Irish protest group, said the person's arm was broken in the incident and that they had to undergo surgery, according to Irish public broadcaster RTÉ. Berlin police confirmed on Saturday that it was aware of video footage of the incident. The officer responsible had been identified and the incident was under review, a spokesman said. So far no proceedings have been launched against the policeman, as the proportionality of his behaviour was still being reviewed, he said. The protester was treated by the fire brigade, the spokesman said, without specifying the nature of their injuries. The person faces an investigation for insulting and resisting officers, police said. There have been a number of clashes between pro-Palestinian protesters and police at rallies across Germany since Israel began its war on Gaza following the Hamas-led massacre on October 7, 2023. German authorities have repeatedly been accused of disproportionately curtailing pro-Palestinian protests, with many demonstrations broken up by a heavy police presence over accusations of anti-Semitism. Police said hundreds of officers were deployed to Berlin's Mitte district on Thursday evening to dissolve an unauthorized gathering "in the context of the Middle East conflict." Some 100 people were said to have been moving between the Rosenthaler Platz and Hackescher Markt squares. Some protesters had displayed "verbally aggressive" behaviour towards officers, with insults, physical attacks and acts of resistance towards police officers occurring during the operation, according to a press release from Friday. A total of 94 people were detained and investigations on suspicion of displaying signs of unconstitutional and terrorist organizations, assaulting and resisting law enforcement officers, insult, assault and suspected unauthorized residence have been initiated.
