A Reuters witness saw the 73-metre (239.5 foot) yacht Clio arrive off the coast of Gocek in the Aegean coastal province of Mugla on Saturday. The Cayman Islands-flagged vessel remains in a bay off Gocek.

NATO member Turkey shares a maritime border with Ukraine and Russia in the Black Sea, has good ties with both and mediates in the conflict. It has supported Kyiv, but also opposed sanctions on Moscow, including measures against Russian billionaires.
