President Donald Trump has now said that the US has forcibly seized an Iranian-flagged cargo ship that tried to get around the US’s naval blockade near the Strait of Hormuz, in the first such interception since the blockade of Iranian ports began last week.He said a US Navy guided missile destroyer in the Gulf of Oman “stopped them right in their tracks by blowing a hole in the engineroom” and that U.S. Marines had custody of the vessel, named Touska, and were “seeing what’s on board!”Iran’s top diplomat has told his Pakistani counterpart that Washington’s demands in negotiations and its threats to Iranian ships and ports mark “clear signs” of America’s disingenuousness.The news threw into question Trump’s earlier announcement that US negotiators would head to Pakistan today for another round of talks with Iran. That had raised hopes of extending a fragile ceasefire set to expire by Wednesday, but Iran has not confirmed it would attend.The escalating standoff threatened to deepen the energy crisis roiling the global economy and push the two countries toward renewed fighting that has killed at least 3,000 people in Iran, nearly 2,300 in Lebanon, 23 civilians and 15 soldiers in Israel, and more than a dozen in Gulf Arab states. Thirteen US service members have also been killed.
