Shipping company Maersk says one of its US-flagged commercial vessels has successfully exited the Strait of Hormuz under US military protection.

A 33-year-old German citizen was detained following the incident, the authorities say.

The operator of the MV Hondius ship says a Dutch husband and wife, as well as a German national, have died but the cause has not yet been established.

The ex-New York mayor 'remains in critical but stable condition', according to his spokesman.

Russia has declared a unilateral ceasefire to cover the event and threatened a massive strike on central Kyiv if it were disrupted.

The 44-year-old will avoid jail time after her arrest in California earlier this year.
