The U.S. carved out an alternate path that runs along Oman's coast and said Saturday that it's been expanded to accommodate inbound and outbound traffic.

The MOU was first tested on Thursday, when Iran fired on a commercial in the Strait of Hormuz, triggering retaliatory strikes from the U.S.

A multinational maritime body overseen by the U.S. Navy said Saturday that it would expand a route near Oman in the strait to allow for both inbound and outbound traffic.
