At least three people were shot dead in an apparent anti-Semitic attack at the Jewish Museum in the Belgian capital Brussels on Saturday.

A lone gunman wearing a rucksack walked into the Jewish Museum and opened fire, before escaping in a waiting car. The man is still at large, although Belgian police are believed to have the car's registration number.

Two women and one man died in the attack. Another person is reported to be in a serious condition in hospital.

Belgian media agencies reported that another 12 people were treated for shock immediately after the incident. A fourth person was seriously wounded, emergency services said. The attack took place at around 15:50 (13:50 GMT) in the central Sablon area of the city.

Belgian Deputy Prime Minister Didier Reynders was one of the first people to arrive at the scene. He said: "I am shocked by the murders committed at the Jewish museum, I am thinking of the victims I saw there and their families."

A representative for the Belgian Foreign Ministry tweeted immediately after the incident to offer the government's condolences to the families of the victims.
