Ukraine’s military has suspended all activity in its commercial ports in the wake of the Russian invasion.

The ban extends to all Black Sea and Azov Sea ports — Odessa, Chernomorsk, Pivdenny (Yuzhny), Nikolaev, Dneprobugsky, Berdyansk and Mariupol, according to the West P&I club.

Vessels currently in the terminals should seek to leave immediately if it is deemed safe to do so, London-based maritime security agency Dryad Global said in a note to clients.
