The Globe and Mail reports in its Thursday edition that the United States launched new air strikes against Iran early Thursday, and Tehran responded by hitting Bahrain, Kuwait and Qatar in crossfire that again threatened an interim deal intended to help end the war in the Persian Gulf. An Associated Press dispatch to The Globe says the strikes came hours after President Donald Trump said recent Iranian attacks on ships in the Strait of Hormuz signalled the end of the fragile ceasefire. The U.S. struck a variety of military sites and port facilities early Wednesday after Iran's targeting of several merchant vessels off the coast of Oman. Thursday's attacks appeared bigger all round, with sirens sounding at least twice in Bahrain, home to the U.S. Navy's 5th Fleet headquarters. There was no immediate word of damage in the three Gulf Arab countries. Kuwait's military said it had intercepted incoming drones and missiles. Military officials said in a social-media post that the latest strikes were intended to "further degrade" Iran's ability "to threaten freedom of navigation" in the strait, which was open to shipping traffic before the U.S. and Israel attacked Iran on Feb. 28. Mr. Trump also threatened more strikes.
