Yemen’s Iran-backed Houthi rebels says they have attacked two Saudi oil tankers in the Red Sea, and the U.S. military said it conducted a 12th night of strikes against Iran as the two countries vie for control of vital shipping lanes. The Houthi attack in the Red Sea announced Thursday threatened to open a new front in a war that has roiled the global economy, sending prices for fuel and other goods surging across the world. Saudi state media reported that a tanker named the Encelia was set ablaze by an attack while sailing overnight in the Red Sea, citing an unidentified source from the General Authority of Transport.

President Donald Trump has chosen not to sign a sweeping housing affordability bill on Friday, in protest of Congress not approving a strict voter ID bill that does not have enough support to pass. Still, the housing measure could become law on Friday without Trump’s signature, as he had 10 days to issue a veto and stop the measure. Trump’s post simply says that he will not sign it.
