“Fighting between the U.S. and Iran intensified overnight, with the American military hitting a wide range of new targets and Tehran claiming it had launched attacks on several of Washington’s allies in the region,” the Wall Street Journal reports.“The skirmishes represented a higher level of military activity between the two foes since a ceasefire went into effect last month and raised hopes of a lasting peace deal. President Trump declared the ceasefire over last week after Iran fired on ships heading through the Strait of Hormuz.”“Now the two sides are locked in a stalemate over the strait, a waterway through which 20% of the world’s oil flowed before Iran effectively shut it down during the war. Trump administration officials have grown pessimistic about ongoing negotiations with Tehran and frustrated about Iran’s continued attacks on Hormuz shipping.”
