JTA reports,

Israeli police prevented the attempted sacrifice of a Passover lamb at the Western Wall.
A group of religious Jews led by far-right activist Itamar Ben-Gvir, lamb in hand, was blocked from reaching Judaism’s holiest site Wednesday.
They said they wanted to slaughter the lamb as part of pre-Passover rituals, but authorities said Ben-Gvir, who is identified with Jews campaigning to establish a Third Temple in place of Al-Aksa Mosque, aimed to provoke Palestinians.
