The Globe and Mail reports in its Friday edition that the United States launched new air strikes against Iran early Thursday, and Tehran responded by targeting U.S.-allied Mideast countries in an exchange of fire that threatened an interim deal intended to help end the war in the Middle East. An Associated Press dispatch to The Globe says the back-and-forth attacks, including a day earlier, have repeatedly threatened the ceasefire. But Thursday's appeared bigger all around, with sirens sounding at least three times in Bahrain, home to the U.S. Navy's 5th Fleet headquarters, and missiles targeting Kuwait and Qatar. Sirens sounded Thursday afternoon in Jordan as well, where the U.S. has stationed troops and aircraft. An Iranian official accused the U.S. of launching an air strike later Thursday targeting the area around Iran's sole nuclear power plant, and other explosions were reported elsewhere in the country during the afternoon. The strikes came hours after President Donald Trump said recent Iranian attacks on ships in the Strait of Hormuz signalled the end of a fragile ceasefire and threatened to escalate the conflict if they didn't stop. Iran said the two days of American air strikes have killed at least 14 people.
