Cairo/Dubai/Washington. Iran fired ballistic missiles at a US ​air base in Jordan on Tuesday and the United States attacked Iranian targets for five hours in a battle for control of the Strait of Hormuz that has pushed up oil prices to ‌four-week highs.

US forces launched waves of attacks for the third successive night after Iran said on Saturday it was closing the strait, prompting US President Donald Trump to reinstate a blockade of Iranian shipping and propose charging a 20% fee to guard the vital waterway.

The strikes have increased doubts that an interim deal agreed last month will lead to a permanent halt in a more than four-month-old war that has disrupted global energy supplies and raised fears of a rise in inflation across the world.

Regional analysts said the hostilities remained ​within controlled boundaries for now, with both sides seeking leverage for an eventual peace deal, but that there was still a risk of fighting spinning out of control.

"I doubt the two sides will resume ​a full war, especially as Trump will suffer — though there is also a distinct possibility that the Iranians will overplay their hand. That is true of Trump too, ⁠of course," said Yezid Sayigh, a senior fellow at the Carnegie Middle East Center.
