At least 30 ultra-Orthodox Jews have been arrested after police cracked down on hundreds of Haredi men blocking the streets of Jerusalem, with some demonstrators insulting the officers by calling them Nazis. Some 500 people belonging to the Jerusalem Faction movement clashed with police on Thursday as security forces tried to clear the crowd that blocked traffic and light rail service, in protest at the detention of an IDF draft-dodger. Dressed in black hats and long black jackets, members of the Haredi community accused the government of attempting to suppress religion. "The draft is religious persecution," they shouted. "To prison but never to the army!"
