Washington released satellite photographs showing what officials said were strikes from the northern Persian Gulf — Iran or Iraq — rather than from Yemen, where the Houthi militia that claimed responsibility for the attacks operates.

Iran rejected as “max deceit” an accusation by Secretary of State Mike Pompeo that it was responsible.

Background: Squeezed by American sanctions, Iran has sought to inflict similar pain on regional rivals, but it has stopped short of a direct attack that might prompt a military response.

Related: The damage could take roughly 5 percent of global oil supplies off the market, but experts said any disruption was unlikely to last.

Another angle: Iran has dismissed the possibility of a meeting between its president, Hassan Rouhani, and Mr. Trump at the United Nations next week, state news media reported today.
