Concerns grew on Monday that the ceasefire between the United States and Iran might not hold after the US said it had seized an Iranian cargo ship that tried to run its blockade and Iran vowed to retaliate.
Efforts to build a more lasting peace in the region likewise appeared to be on shaky ground, as Iran said it would not participate in a second round of negotiations that the US had hoped to kick off before the ceasefire expires on Tuesday.
The US military said on Sunday it fired on an Iranian-flagged cargo ship as the vessel sailed toward Iran’s Bandar Abbas port. “We have full custody of their ship, and are seeing what’s on board!” President Trump wrote on social media.
