A US Navy P-8 Poseidon aircraft began patrol flights over the Black Sea on Tuesday at Bulgaria's request, Prime Minister Rumen Radev said, after a series of drone attacks on merchant ships off the Bulgarian and Romanian coasts, Slovak outlet Aktuality.sk and Austria's Die Presse reported. The aircraft is carrying out reconnaissance missions and watching for "activity that could pose a threat", Radev said.

The plane flew from Sicily and landed in the Bulgarian port city of Varna on Sunday, according to flight-tracking data cited by Aktuality.sk and Die Presse. Radev said the deployment followed consultations with NATO and other partners, and that Sofia expected further support; how long the aircraft stays will depend on how the situation develops.

Four ships were attacked by drones near the Bulgarian coast this month; two of them sank, and 21 sailors remain missing, according to Die Presse and Kronen Zeitung. One of the stricken vessels was Ukrainian, prompting Bulgaria to summon Russia's ambassador and open an investigation into a possible war crime, Aktuality.sk reported.

Teams from allied countries, equipped with advanced equipment, were due to arrive in Bulgaria to help investigate the drone strike on one of the ships, the Chelsea 3, Radev said, according to Romanian outlet G4Media. Investigators are examining recovered debris and carrying out chemical analysis to identify the type of explosive used, he said.

Radev rejected claims that commercial shipping had been disrupted, saying vessel traffic had continued and that traffic through the port of Burgas had in fact increased, G4Media reported. Bulgaria has not formally blamed Russia or Ukraine for the attacks, saying it is waiting for conclusive evidence, Die Presse reported.

EU foreign policy chief Kaja Kallas said on Tuesday that Russia's intensifying attacks in the Black Sea risked triggering a global food crisis, and called on Moscow not to further obstruct Ukrainian grain exports, Die Presse and Kronen Zeitung reported. The Black Sea is a key route for global grain, energy and raw material exports.

Why it matters for Europe

The Black Sea carries much of the world's grain, energy and raw-material exports, and the string of drone attacks on commercial vessels off two NATO members' coasts has already sunk two ships and left 21 sailors missing. A US reconnaissance aircraft patrolling from a NATO member's territory, alongside allied forensic teams examining drone debris, marks a direct alliance response to attacks Sofia has so far declined to blame on any specific state.
