The Metropolitan Transportation Authority approved new guidelines for advertisements on Thursday, prohibiting those that it “reasonably foresees would imminently incite or provoke violence or other immediate breach of the peace.”

The 8-to-0 vote by the authority’s board came three days after pro-Israel ads characterizing Islamist opponents of the Jewish state as being “savage” began appearing in subway stations, setting off vandalism, denunciations of the authority and calls for the ads’ removal.

The authority had initially rejected the ads, citing their “demeaning” language. The group responsible for the ads, the American Freedom Defense Initiative, sued, and in July won a federal court ruling on First Amendment grounds.

“We’ve gotten to a point where we needed to take action today,” Joseph J. Lhota, the authority’s chairman, said at a news conference on Thursday.
