ISTANBUL—A Russian shipping line with ties to the country’s Defense Ministry has been ferrying weapons and supplies through the Bosporus to ports on the Black Sea in support of Moscow’s war effort, according to Ukrainian officials who have urged Turkey to block their access.
Kyiv has asked Turkish authorities to take action against at least four cargo ships that it says are transporting military equipment from a Russian base in Syria through straits controlled by Turkey, the only way into the Black Sea from the Mediterranean.
