U.S. Navy, Iran ships have close encounter in Middle East

The frigate came within 150 yards of the USNS Invincible on Thursday in the Gulf of Oman, just south of the strategic Strait of Hormuz. The gulf separates Oman from southeastern Iran.

The encounter was deemed “unprofessional” but not unsafe because the frigate was on a parallel course with the Invincible at the point of closest approach.
