The Pentagon says at least four service members are dead after a refueling aircraft supporting the U.S. bombing of Iran crashed in western Iraq on Thursday. The Pentagon has not revealed the fate of two other crew members, saying that “rescue efforts continue.”

This comes as a coalition of 250 prominent organizations sent a joint letter to Congress urging lawmakers to vote against any additional funding for the U.S.-Israeli war on Iran. The groups include the ACLU, Public Citizen, Greenpeace, Jewish Voice for Peace and the Service Employees International Union. They write, “The $50 billion that the administration reportedly seeks for a new Pentagon supplemental would be enough to restore food assistance for four million Americans that was taken away in the tax and budget reconciliation bill, establish universal pre-K education, and pay for the annual construction of more than 100,000 units of housing, among other possible priorities.”
