Russia manages to transport S-300 missiles through Bosporus from its bases in Syria

"Russia has managed to transfer missiles for the S-300 air defense complex through the
Bosporus to the Black Sea from its bases in Syria.

It is noted that Turkey has closed the Bosporus to warships, so Russia cannot transfer its warships from the Mediterranean Sea to the Black Sea.

The merchant ship Sparta II crossed the strait.

Sparta II's destination was Novorossiysk, a Russian port and major naval base near the Kerch Bridge. Naval News writes that the S-300 missiles should strengthen the Russian "defense" near Kerch or in other areas." UkrainianNews
