Greece owns one of the world's largest merchant fleets and has been directly affected by repeated Black Sea attacks throughout 2026. On July 22, 2026, Greece's Shipping Ministry issued an advisory recommending that all Greek-flagged commercial ships upgrade security measures when sailing in the Black Sea, citing "increased tension" following the string of tanker attacks . This follows earlier Greek actions: in January 2026, Athens warned ship operators to reassess security protocols for Russian ports after drone strikes on two Greek-managed tankers (Matilda and Delta Harmony)
. In March 2026, a Greek-flagged oil tanker was also hit by a projectile or drone near Novorossiysk
. Greece has formally condemned attacks on civilian ships of Greek interests, warning that such incidents endanger crew safety and the marine environment
.
Ukraine's acting Foreign Minister, Andrii Sybiha, said that at least three civilian cargo ships had been attacked by Russia in recent days and that, as a result, zero vessels were passing through Ukraine's Black Sea grain corridor . Ukraine has formally requested an emergency meeting of the UN Security Council for July 27, 2026
. Sybiha warned: "Millions of families across Africa, Asia, the Middle East, and Latin America may face rising prices and hunger if this terror continues"
. He urged all states, particularly those affected, to demand Russia stop its attacks on civilian shipping

Ukraine has been conducting an intensifying offensive drone campaign against Russia's "shadow fleet" —tankers and cargo ships that Russia uses to evade sanctions and supply its forces. Key details:
