In Brussels, Belgium, police fired water cannons at far-right demonstrators who stormed a memorial for victims of last week’s deadly attacks, chanting nationalist slogans and making Nazi salutes. The tensions came as Belgian authorities carried out new raids Sunday following Tuesday’s attacks on the Brussels Airport and subway that killed at least 31 people, including four Americans. Three men arrested in the raids have been charged with terrorism-related offenses after a number were charged over the weekend, including Faisal Cheffou, who unconfirmed reports say is suspected of being the third man shown in footage from the Brussels Airport, next to two men who blew themselves up. Over the weekend, authorities in Italy, Germany and the Netherlands also arrested suspects in the attacks in Brussels and the November attacks in Paris that killed 130 people.
