In the United States, some labor unions, city governments and town councils have weighed in on the Israel-Hamas war, issuing statements in support of a cease-fire — often over vociferous objections from some of their own members and constituents.

On Wednesday night, the school board in Ann Arbor, Mich., became one of the first public school districts in the country to vote in favor of such a statement.

Supporters of the resolution, including Palestinian American and Jewish board members, said that the statement was an urgent moral necessity amid a humanitarian crisis.

But the vote — 4 to 1, with two members abstaining — was divisive in Ann Arbor, home to the University of Michigan and sizable Arab and Jewish populations.
