Security has been stepped up at Jewish sites across Belgium after a gunman shot dead three people at the Jewish Museum in the capital Brussels.
A man who was detained by police shortly after the attack has been released without charge. A manhunt has been launched for a different suspect.
A fourth victim remains in a critical condition.
Two of the dead were Israeli tourists, a couple in their 50s, Israel’s foreign ministry said on Sunday.
The Belgian prosecutor’s office said the victims were struck by bullets in the face or throat and Brussels Mayor Yvan Mayeur said he thought the shooting was probably a “terrorist act”.
Israeli Prime Minister Benjamin Netanyahu issued a statement strongly condemning the killings which he said were “the result of endless incitement against the Jews and their state”.
Belgium has a Jewish population of some 42,000, about half of whom live in the capital.
Belgian Foreign Minister Didier Reynders, who was one of the first people to arrive at the scene, said: “You cannot help think that when we see a Jewish museum, you think of an anti-Semitic act. But the investigation will have to show the causes.”
Belbium’s Prime Minister Elio Di Rupo said “everything has been mobilised that can be mobilised” to find the killer.
It is believed the shooter parked a car outside before entering the museum, firing and leaving the scene quickly.
