The New York Times reports that:
A precarious cease-fire took effect in parts of Yemenon Tuesday night, in the first negotiated halt to hostilities since Saudi Arabia started a bombing campaign against Yemen’s Houthi rebels in late March.
There were reports of clashes and at least one airstrike in the southern city of Aden, a major confrontation point in Yemen’s war ...
An Iranian ship, meanwhile, is on its way to Yemen. Iran says it is carrying “emergency relief supplies.”
When Iran recently attempted to send supplies into Yemen, by air, “the Saudi-led coalition bombed the airport in the Yemeni capital, forcing the Iranian plane to turn back.”
Now, during the ceasefire, Iran is Iran will attempt the resupply by sea and as Reuters reports, “Iranian warships will escort the vessel.”
Iran is warning other nations not to interfere.
"The 34th fleet, which is currently in the Gulf of Aden, has special responsibility to protect the Iranian humanitarian aid ship," Admiral Hossein Azad said.
This fleet consists, evidently, of “a destroyer and support vessel.”
The U.S. Navy also has ships, to include the carrier Theodore Roosevelt, on station.
"We would discourage any provocative actions," said U.S. State Department spokesman Jeff Rathke.
