Prosecutors charged a Belgian man, who stabbed two police officers, with attempted terror-related murder and being part of a terrorist group on Thursday and detained his brother.
The man, 43-year-old Belgian Hicham D, stabbed one officer in the neck and another in the stomach and broke the nose of a third. Named by media as Hicham Diop, he was then shot in the leg and taken to hospital.
Belgian media said Diop was a former soldier who may have had a grudge against the police after being hit accidentally by a police car in 2011.
His brother Aboubaker D, a Belgian born in 1970, was detained on Thursday afternoon. A special counter-terror judge will decide on Friday whether he should remain in custody.
Brussels is on high alert after bombings in March killed 32 people at the city’s airport and in a subway carriage.
