2. Four people were killed on Saturday in a shooting at the Brussels Jewish Museum. Police detained one suspect who was at the scene late Saturday, but he was released and is now considered a witness.
Photographs and video from the Jewish Museum of Belgium show the gunman behind Saturday’s deadly attack entering the building, opening fire, and walking away. He carried out the assault with an AK-47 rifle, police said Sunday.
3. Images released by Belgian police show that the gunman wore a cap and blue shirt. He carried two bags over his shoulder.
His face is not clear in the images. Authorities are searching for the suspect, and believe that he acted alone, deputy public prosecutor Ine Van Wymersch said.
4. Although the motive remains unknown, Belgian Foreign Minister Didier Reynders says “you cannot help to think that when we see a Jewish museum, you think of an anti-Semitic act.” Anti-terror measures have been ordered for Jewish sites around Belgium.
5. The Belgian Prime Minister, Elio Di Rupo, confirmed the shooting and tweeted his condolences.
Shocked by the events in Brussels. My sincere sympathy and support for the families and loved ones of the victims
