Tehran has "no trust" in the US and is interested in negotiating with Washington only if it is serious, Iranian Foreign Minister Abbas Araqchi said on Friday, as talks on ending the war remained on hold.

Araqchi told reporters in New Delhi that all vessels can pass through the Strait of Hormuz except those "at war" with Tehran, if they coordinate with Iran's navy.

But the situation around the waterway, vital to global energy and commodities markets, was "very complicated", he added, during a visit to attend a BRICS foreign ministers' meeting in India.
