BRUSSELS (Reuters) – Belgian police were hunting on Sunday for an assailant who shot dead three people at the Jewish Museum in Brussels, and French authorities tightened security at Jewish sites following another attack that prompted fears of a rise in anti-Semitism.
Belgian authorities said a French woman and an Israeli couple died and a Belgian man was seriously wounded on Saturday after being shot in the face and neck.
