Black Sea and black ops: How exposed is Europe to Ukraine war spillover?

The story is as underreported as it is consequential for the entire planet. Three Turkish-owned cargo ships out of Ukraine have been hit in EU waters by suspected Russian drones. One, the Togo-flagged Alfa Watan, sunk on Tuesday off Bulgaria. Ten Egyptian and Syrian crew members are missing. For its part, Ukraine has been hitting Russian tankers in the Black Sea, with no sign of a return to a UN-brokered deal to allow oil, grain and fertiliser ships to pass.
