WASHINGTON — In a rare punitive move against Israel, the State Department said Tuesday that it will impose travel bans on extremist Jewish settlers implicated in a rash of recent attacks on Palestinians in the occupied West Bank.

Secretary of State Antony Blinken announced the step after warning Israel last week that President Joe Biden’s administration would be taking action over the attacks. Blinken did not announce individual visa bans, but department spokesman Matthew Miller said the bans would be implemented starting Tuesday and would cover “dozens” of settlers and their families, with more to come if the settler violence continued.

The decision comes at a sensitive moment in U.S.-Israeli relations. The Biden administration has firmly backed Israel since it was attacked by Hamas on Oct. 7, even as international criticism of Israel has mounted.

In recent weeks, the administration has stepped up calls on Israel to do more to limit civilian casualties as the Israelis expand their offensive and target densely populated southern Gaza. The U.S. has refrained from outright criticism of that offensive. It has been increasingly outspoken, however, about settler violence in the West Bank and Israel’s failure to respond to U.S. calls to stop it.

The U.N. Office for the Coordination of Humanitarian Affairs said Monday that since Oct. 7 at least eight Palestinians in the West Bank have been killed by settlers. The U.N. agency said it has recorded 314 attacks by settlers that have resulted in Palestinian casualties, damage to Palestinian-owned property or both, and in nearly half of the attacks the settlers were accompanied or actively supported by Israeli forces.
