The rating measures how well the claim that Russia launched these strikes is supported by evidence, not how plausible it seems. Any one of these would move it.

• partly seenPhysical evidence: recovered drone debris, a drone type or serial numbers, published by Bulgaria, Romania or a technical body such as the EU's maritime agency.
• partly seenAn official finding: Bulgarian or Romanian prosecutors or ministries naming the attacker on the basis of an investigation, not "logic." Romania's foreign minister says “Russia bears full responsibility”; she says investigations are under way, and no finding or evidence has been published (X). President Dan says it is “too early” to say for sure; army and intelligence teams are investigating (Politico); on Oct. 16 he added that “intuition tells us” Russia is the beneficiary of the uncertainty, and said France had offered military equipment until Romania’s own orders arrive (Euronews Romania). Asked Oct. 16 whether the drone was Russian, Țoiu said the technical investigation is not finished (Digi24). Bulgarian Prime Minister Rumen Radev: it is “logical to assume” Russia, “but we do not have convincing evidence”; Bulgaria will examine an attacked ship for drone fragments (Babel).
• not seenAllied attribution with evidence: NATO, the EU, the US or Turkey attributing the strikes and citing radar, satellite or signals data. On Oct. 22 the EU’s foreign-policy chief, Kaja Kallas, wrote of “Russia’s intensifying attacks on Black Sea shipping” after meeting Romania’s foreign minister, without citing evidence or saying which attacks she meant (X).
• not seenA claim or credible denial of responsibility by Russia's Defence Ministry or Ukraine, with specifics.
• seenAnother strike in Bulgarian or Romanian waters, or one inside their 12-mile territorial seas. The Yara J was hit inside Romania's territorial waters on Oct. 14 (Reuters); Romania's foreign minister says four ships were targeted in 24 hours, including in its territorial waters (X).

• Five ships hit on three nights. October 5: the Royad Mammadov, carrying Ukrainian corn, caught fire and sank off Romania; Romania reported two dead and 11 rescued (Reuters). October 6: the Alfa Watan sank almost instantly about 70 nautical miles east of Bulgaria; all ten crew, nine Syrian and one Egyptian, are presumed dead. The Able, carrying wheat, was set ablaze and its 18 crew rescued (Reuters, Al Jazeera). Night of October 12–13: the Ukrainian-owned Chelsea 3 was hit three times by drones (Bulgarian officials have described them both as aerial and as sea drones) and all 15 crew were rescued; the HS Dignity sank 17 nautical miles off Krapets, with five rescued and 11 missing, a figure officials call preliminary (AFP, 24chasa). Earlier, on August 27, the PROGRESS IV sank about 20 nautical miles off Romania's Sfântu Gheorghe after what Romania's defence minister said was a drone strike; all 12 crew were rescued, and prosecutors opened a criminal case that includes operating an unmanned aircraft carrying explosives (Gândul).
• Romania's president says drones hit two tankers off Sulina. On October 15 Nicușor Dan said the Yara J and the Wine Trader had been “hit” by “air drones” (AFP), but declined to say whether Russia was responsible. A NATO military source, not named, told Reuters the drones “were of Russian origin” (Reuters). Moscow said it hit two cargo ships carrying military cargo to Odesa, without naming them (BBC); the Wine Trader was empty (AFP).
• October 23: the Khoryv. The Comoros-flagged cargo ship, with 10 Ukrainian and three Azerbaijani crew, sank about 13 nautical miles off Constanța, just outside Romania’s territorial waters; nine crew were rescued, one was found dead and three are missing (Agerpres; Reuters). President Nicușor Dan said it had been hit by a drone and called the attack “part of Russia’s escalation process in its war in Ukraine” (Reuters).
• Most of the ships are not Ukrainian. Three of the five are Turkish-owned or Turkish-managed; only the Chelsea 3 is Ukrainian-owned. Two carried Ukrainian grain; the cargo of the two that sank in Bulgarian waters has not been published (Reuters).
• Bulgaria has moved, but has no evidence in hand. On October 9 Defence Minister Dimitar Stoyanov said it was "entirely possible" the drone was Ukrainian or Russian, and that no debris had been found (Club Z). On October 13 he said it would be "illogical for the Ukrainians to strike their own ships. Under these circumstances, we assume the drones are Russian." Prime Minister Rumen Radev wrote that "logic suggests the outcome works to the advantage of the Russian Federation," and summoned Russia's ambassador (AFP). Before the EU summit in Brussels he added: “we do not have convincing evidence” (Babel). Radev has also said Bulgaria lacks "solid and clear evidence" against either side (Reuters). On October 14 he told parliament: “The logic points in that direction. The problem is that we cannot prove it” (AP).
• Bulgaria has material from the Chelsea 3. The ship was towed to Burgas on October 17. Investigators seized burned wiring, glass fragments and swabs from its three holes and ordered an explosives analysis to identify the drone, with foreign partner services joining; no military cargo was found aboard. The Able, hit on October 6, is believed to have sunk overnight on October 19–20 (BNT; Maritime Executive).
• Bulgaria’s analysis of material from the Chelsea 3 is pending. Inspectors found no drone remains on the burned-out Able (Club Z). Bulgaria has asked the EU's maritime safety agency, the US and NATO for technical help, and says it will name the attacker only after technical analysis. On October 14 Radev told parliament the Chelsea 3 will be towed to Varna this week for a thorough inspection, and that Bulgaria expects deep-water equipment to examine both wrecks (Mediapool; Novinite, Capital).
• Russia denies targeting the first two ships. Its embassy said they were "not among the targets" hit by Russian forces (Fakti), and its ambassador did not rule out a "provocation by a third party" (Reuters). Russia's Defence Ministry has made no public comment on the October 13 strikes. It claims near-daily drone strikes on cargo ships "at sea" bound for Ukrainian ports, without naming ships or locations (Telegram); Britain told the OSCE that on October 5 the ministry announced strikes on "two cargo vessels in the Black Sea" (GOV.UK).
• Both sides use drones against Black Sea shipping. Russia strikes Ukrainian ports and Ukraine-bound ships; Ukraine strikes Russian tankers and grain ships. The maritime risk firm Ambrey counted at least 45 merchant ships attacked in the past 12 months in waters with no attacks the year before (AFP). Turkish-owned ships have been hit on both sides: in August two were struck by drones after leaving Russia's port of Novorossiysk (Turkish Foreign Ministry). That is why attribution here is not obvious.
• Romania shot down two drones over its waters. On October 17, Romanian F-16s downed two drones that entered Romanian airspace, after radar tracked a group of targets about 120 km east of Snake Island heading southwest. Both were shot down over Romania’s territorial waters. The Defence Ministry has not said whose drones they were or what they were aimed at (Romanian Defence Ministry). On Oct. 18 Defence Minister Radu Miruta said the drones were flying at 450 km/h, “which leads us to think they were Russian-made Geran-4 drones,” the first of that kind Romania has shot down (Reuters). The Foreign Ministry put the shootdowns 20–25 km east and southeast of Sulina, and said Romania has called a meeting of NATO’s North Atlantic Council on Tuesday on Black Sea defence and deterrence (Romanian Foreign Ministry). Romania’s Defence Ministry counts six drones shot down and 35 unauthorized incursions into its airspace or waters this year, plus 44 drones or fragments found on its territory and two drifting sea mines neutralized (Euronews Romania).
• On Oct. 16 Bulgarian Defence Minister Dimitar Stoyanov said Sofia had asked NATO’s Secretary General and Supreme Allied Commander to strengthen its capabilities, “which also means deploying additional forces on our territory,” including anti-drone systems; a NATO official said allied ambassadors would discuss it this week (Reuters via Daily Maverick).
