WASHINGTON - The U.S. military signaled on Friday it may allow warships to accompany other nations’ vessels through the Strait of Hormuz, after Iran’s seizure of a container ship this week prompted the Navy to start accompanying U.S.-flagged vessels. “Our current plans are for accompanying U.S.-flagged ships, although there are discussions with other nations to include their vessels as well,” said Colonel Patrick Ryder, a spokesman at the U.S. military’s Central Command, declining to identify the other countries.
