Iran threatens to block all regional oil routes in response to U.S. Strait of Hormuz blockade

Iran on Wednesday threatened to block all oil export routes in the region in retaliation for a U.S. maritime blockade of Iranian ports in the Strait of Hormuz. The escalating standoff between Washington and Tehran could threaten global oil markets. The Strait of Hormuz is one of the world's most critical energy transit chokepoints.
