(Reuters) — The shooting of three people at Brussels’ Jewish Museum was probably a “terrorist attack”, Belgian officials said on Monday, though some security experts suggested it may have been the work of a hitman rather than an anti-Semitic ‘lone wolf’.
An Israeli couple and a French woman were killed in the shooting on Saturday. A Belgian man remains in critical condition in hospital. The gunman is on the run.
Police released a 30-second video clip from the museum’s security cameras showing a man wearing a dark cap, sunglasses and a blue jacket enter the building, take a Kalashnikov rifle out of a bag, and shoot into a room, before calmly walking out.
A spokeswoman for the federal prosecutors told reporters the killings were being treated as a likely terrorist attack but other possibilities were not being ruled out.
“The fact that all lines of inquiry remain open means that we have no certainty about it being a terrorist attack but it seems very likely to us,” spokeswoman Wenke Roggen said.
“The footage shows a person who seems cold blooded and determined,” she added.
Some security experts said the way in which the assailant carried out the killings suggested planning and execution by a specialist.
