President Donald Trump warned the U.S. will “obliterate” Iran’s power plants if it doesn’t fully open the Strait of Hormuz within 48 hours, prompting Tehran to say it would respond to any such strike with attacks on U.S. and Israeli energy and infrastructure assets in the region.

Iranian missiles, meanwhile, struck two communities in southern Israel late Saturday, leaving buildings shattered and dozens injured in dual attacks not far from Israel’s main nuclear research center.

Major developments we’re following:

A dangerous new threat: Iran targeted the joint U.K.-U.S. Diego Garcia military base in the Indian Ocean about 2,500 miles (4,000 kilometers) away, suggesting that Tehran has missiles that can go farther than previously acknowledged — or that it had used its space program for an improvised launch.Pressure increases to get shipping back on track: As Iran threatens shipping on the Strait of Hormuz, the United Arab Emirates joined 21 other countries including the U.K., Germany, France and Japan in expressing “readiness to contribute to appropriate efforts to ensure safe passage.”The death toll from the war has risen to more than 1,500 people in Iran, more than 1,000 people in Lebanon, 15 in Israel and 13 U.S. military members, as well as a number of civilians on land and sea in the Gulf region. Millions of people in Lebanon and Iran have been displaced.
