Ankara escalated its diplomatic response to the Russia–Ukraine war's maritime spillover on December 4, summoning both Ukraine's ambassador and Russia's acting chargé d'affaires to the Foreign Ministry following a week of attacks on tankers in or near Turkish waters. Deputy Foreign Minister Ayşe Berris Ekinci told parliament the country is "observing a very serious escalation in the Russia–Ukraine conflict," marking Turkey's most assertive formal intervention since drone and missile debris began landing on its Black Sea neighbors. President Recep Tayyip Erdoğan declared such strikes "unacceptable," while Foreign Minister Hakan Fidan called them "very scary," warning they threaten regional safety and demonstrate the war's expanding geographic reach.
The dual summons signals that unmanned maritime strikes inside Turkey's Exclusive Economic Zone have crossed a threshold for Ankara—legally distinct from territorial waters but politically sensitive enough to demand formalized pressure on both belligerents. With Black Sea shipping insurance rates climbing, a major Turkish operator suspending Russia-related voyages, and energy infrastructure directly hit, Turkey is attempting to enforce red lines that balance three competing imperatives: Montreux Convention gatekeeping, energy-security continuity, and NATO coordination without importing the war into littoral jurisdiction.
Timeline of escalation
The November 28 attacks on tankers Kairos and Virat inside Turkey's EEZ prompted the first official condemnation. Foreign Ministry spokesperson Öncü Keçeli stated the strikes posed "serious risks to navigation, life, property and environmental safety." Ukraine-linked sources acknowledged using naval drones against two empty tankers bound for a Russian port; crews were reported safe. One day later, a Ukrainian naval drone damaged a mooring platform at the Caspian Pipeline Consortium terminal near Novorossiysk, briefly halting operations at a facility handling over one percent of global oil supply and the bulk of Kazakhstan's exports.
On December 2, the Russian-flagged tanker Midvolga 2 reported a drone attack approximately 80 miles off the Turkish coast; Kyiv denied involvement in that incident. The sequence culminated in Erdoğan's public declaration and the December 4 summons. Separately, Turkish shipper Beşiktaş Shipping paused all Russia-related operations over security concerns, while another Beşiktaş vessel sustained damage from external impacts near Senegal—no claim of responsibility emerged. The operational pause and rising premiums translate the security crisis into a real-economy problem for Turkish ports and regional freight networks.
Energy security at the nexus
Energy Minister Alparslan Bayraktar urged "all parties" to keep energy infrastructure out of the war and maintain uninterrupted flows, underscoring Ankara's concern that Ukraine's campaign against Russia's oil revenue stream now directly threatens Turkish equities. The CPC mooring strike is the clearest illustration: interruptions ripple beyond Russia to Kazakhstan's economy and global supply chains. Turkey itself imports significant volumes of Russian gas under long-term contracts while pursuing diversification through Azerbaijani and Eastern Mediterranean sources; any sustained disruption to Black Sea energy logistics complicates those balancing equations and raises questions about insurance underwriting for mixed-origin cargoes transiting Turkish straits.
Turkish officials have framed energy continuity as a regional public good, distinct from sanctions enforcement or revenue interdiction. That framing allows Ankara to press Kyiv on operational restraint without endorsing Russian shadow-fleet practices or compromising its NATO commitments. It also positions Turkey to convene littoral-state discussions on rules of the road for unmanned systems, insurance thresholds, and environmental liability—a governance layer that could reduce gray-zone risk even as the broader conflict persists.

What comes next
Ankara has stepped up naval patrols and issued formal warnings; the immediate question is whether those measures translate into operational deconfliction. Insurance markets will price the new risk environment quickly, potentially diverting traffic or raising costs for Turkish and regional shippers. Any further strikes inside Turkey's EEZ—or, more dangerously, its twelve-nautical-mile territorial waters—would likely trigger harsher responses, including potential equipment interdiction or closure of strait access for specific cargo categories.
Diplomatically, the dual summons opens space for Ankara to broker risk-reduction understandings: geographic buffers, advance notification for naval operations, or insurance-pool arrangements that separate commercial liability from sanctions enforcement. Whether Kyiv and Moscow accept such frameworks will depend on battlefield dynamics and their willingness to grant Turkey the mediating role it seeks. For now, Ankara has drawn a line, backed it with formal démarches, and signaled that Black Sea energy flows and navigational safety are non-negotiable—even as the war's unmanned maritime frontier continues to expand.
