Strait wrestle continues

A fragile truce in the Middle East was under strain on Tuesday after the U.S. and Iran exchanged fire in the Gulf as they wrestled for control of the Strait of Hormuz.

Iran's parliament speaker, Mohammad Baqer Qalibaf, said in a social media post on Tuesday breaches of the four-week-old ceasefire by the United States and its allies had endangered shipping and energy transit through the vital waterway.

"We know well that the continuation of the current situation is unbearable for the United States, while we have not even begun yet," he said.

The U.S. military said on Monday it destroyed six Iranian small boats, as well as cruise missiles and drones, after President Donald Trump sent the navy to escort stranded tankers through the strait in a campaign he called "Project Freedom".

The narrow waterway, which carries a large share of global supplies of oil, fertiliser and other commodities, has been virtually closed since the U.S. and Israel began attacks on Iran on February 28, causing price rises around the world.

Several merchant ships in the Gulf reported explosions or fires on Monday, and an oil port in the United Arab Emirates, which hosts a large U.S. military base, was set ablaze by Iranian missiles.

Iranian Foreign Minister Abbas Araqchi said Monday's events showed there was no military solution to the crisis. He said peace talks were progressing with Pakistan's mediation, and warned the U.S. and the UAE against being drawn into a "quagmire."
