PARIS—Pro-Palestinian protesters tried to force their way into a Paris synagogue Sunday with bats and chairs, then fought with security officers who blocked their way, according to police and a witness. Recent violence in Gaza has raised emotions in France, home to western Europe’s largest Muslim population and largest Jewish community. Sunday’s unrest by a few dozen troublemakers came at the end of sizable protest in the French capital demanding an end to Israeli strikes on Gaza and accusing Western leaders of not doing enough to stop them. Prime Minister Manuel Valls said two Paris synagogues had been targeted by unspecified violence that he called “inadmissible.” In a statement, he said, “France will never tolerate using violent words or acts to import the Israeli-Palestinian conflict on our soil.” A police spokeswoman said the Don Isaac Abravanel synagogue in eastern Paris was targeted during a service, and worshippers were blocked inside while police pushed protesters back. The spokeswoman said all those inside left safely by Sunday evening. Aline Le Bail-Kremer watched the incident unfold from her window across the street. She said protesters came from two directions and converged on the synagogue, grabbing chairs from sidewalk cafes and wielding bats as they tried to push past security guards.
