CAIRO, July 23 (Reuters) - Iran's Houthi allies in Yemen said on Thursday they struck two Saudi oil tankers as part of a naval blockade on Saudi Arabia, threatening to create a second chokepoint on global oil supplies alongside the near closure of the Strait of Hormuz.
Two weeks since the effective collapse of an interim truce meant to end the war, the U.S. military launched another nightly round of air strikes on Iran, prompting Iran to fire at neighbouring Arab countries that house U.S. bases.
