Greece advises fleet to boost security in Black Sea after attacks

ATHENS, July 22 (Reuters) – Greece has advised Greek-flagged commercial ships to upgrade security measures when sailing in the Black Sea following a string ​of attacks on tankers over the past ‌days, according to a shipping ministry advisory seen by Reuters.

Greek-operated ships are among the world’s largest fleets of tankers and are pivotal for trade across the Black Sea region, whose ‌waters ​are shared by Bulgaria, Georgia, ⁠Romania and Turkey, as ⁠well as warring Russia and Ukraine, which Moscow invaded in February 2022.

In recent weeks, Ukraine and Russia have stepped up attacks on vessels and other ​facilities in the Black Sea and the Sea of Azov, trying to undermine each other’s war ⁠efforts.

On Sunday, a Russian missile ⁠struck a ship carrying corn near Ukraine’s ​southern port of Odesa, killing 10 people.

Two Greek-operated tankers ​were also attacked with sea drones on Sunday ‌at the Caspian Pipeline Consortium — a 940-mile (1,510 km) oil pipeline connecting Kazakhstan’s Caspian Sea oil fields with Russia’s Black Sea port of Novorossiysk. CPC accounts for ⁠about 80% of Kazakhstan’s oil exports.

The crude oil tanker ASIA, which is managed by Dynacom, and NISSOS IOS, owned ⁠by Kyklades Maritime ‌Corp, were attacked during loading operations. ⁠A third Greek-operated vessel has also ​been ‌attacked in the area, the July 21 ​advisory said.

“Taking ⁠into account the increased tension observed with attacks against commercial ships, it is recommended that all Greek ships in the wider region increase security measures,” the advisory said.
