Iran suspends Switzerland quadrilateral talks after Trump warns it will be hit “very hard”

Iran halted quadrilateral technical talks in Switzerland with the US, Qatar and Pakistan after President Donald Trump publicly threatened to hit Iran “very hard.” The discussions had been focused on licences for Iranian oil sales, the release of frozen Iranian assets and a maritime security mechanism for safe passage through the Strait of Hormuz. Tehran said technical work had made progress, but it withdrew from the four-party format following the US warning. The move underscored renewed Gulf geopolitical tensions that have unsettled expectations for stable crude supply.
