Shipping groups warned Monday that it was too soon to start sailing through the Strait of Hormuz following US and Iranian promises that the trade route would reopen under their agreement to end the war.
US President Donald Trump on Sunday declared: "Ships of the World, start your engines. Let the oil flow!", as he announced the agreement to halt the conflict.
A "memorandum of understanding" between the two nations stipulated the "reopening of the Strait of Hormuz within 30 days", as quoted by Iran's Mehr news agency.
