NATO is deploying additional military assets to the Black Sea amid a deadly escalation of attacks on merchant shipping, as five more vessels were attacked on Tuesday, The Guardian reported. NATO spokeswoman Allison Hart said ambassadors met in the North Atlantic Council on Tuesday to discuss Black Sea security. 'NATO has already strengthened our posture along the eastern flank, including with counter-drone capabilities. NATO will be sending additional assets to the region, including support for surveillance, reconnaissance, and forensics,' Hart said. Reuters, via The Straits Times, reported the deployment will include maritime patrol aircraft, radar systems and drones.

Col. Martin O'Donnell, a spokesman for NATO's Supreme Headquarters Allied Powers Europe, said allies 'have or will send additional maritime patrol aircraft, radar systems, explosive exploitation teams, intelligence personnel, drones, and more to the Black Sea,' Arab News reported. 'The most important thing we can do, however, is to increase our situational awareness in the region through increased sensors and data sharing,' he added. Bulgaria's Prime Minister Rumen Radev said a US P-8 Poseidon aircraft had begun patrolling the Black Sea after Sofia appealed for help, and that Bulgaria expects further assistance, Arab News reported.

Russia's military said it struck three cargo vessels in Ukraine's port of Reni and two other cargo vessels en route to Odesa, The Guardian reported — a claim reported as Russia's own statement. NATO, Bulgaria and Romania have not officially blamed Moscow for the attacks on shipping near their coasts, Arab News noted, although concern has grown after alleged Russian attacks edged into the territorial waters and exclusive economic zones of Bulgaria and Romania. Romania deployed jets over the weekend to shoot down two suspected Russian drones over its territory, and its defence minister, Radu Miruta, said the drones were probably latest-generation Russian Geran-4 drones flying at 450 km/h — 'the first time we've shot down drones like these,' he said, as reported by The Guardian.

The human cost is rising: at least five other cargo ships have been hit near the coasts of Romania and Bulgaria in the past two weeks, with 23 sailors reported dead or missing, most of those incidents outside NATO territorial waters, The Guardian reported. Two chemical tankers were hit by drones last week near Romania's coast by the Sulina canal, a Danube export route for Ukraine. Romania has recorded 35 unauthorised drone incursions so far this year, compared with nine in 2025, and has downed six drones this year, The Guardian reported. Bulgaria has asked NATO for combat aircraft and anti-drone systems, and France sent a maritime reconnaissance aircraft to Romania on 18 October. The maritime risk analyst Ambrey estimated Russian forces were responsible for 80 percent of the attacks — an analyst's estimate, reported as such — and said insurance prices for Black Sea passage have rocketed, with a London market high-risk designation now covering all of the Black Sea except the territorial waters of Romania, Bulgaria and Turkey.
