Tanker Acers hit by projectiles off Qatar as Gulf attacks spread beyond Hormuz
The MR2 chemical tanker was struck 51 nautical miles north of Madinat ash Shamal; a containership drew fire in the Red Sea
The Antigua and Barbuda-flagged tanker Acers was struck by multiple projectiles in the Arabian Gulf at about 19:00 UTC on Wednesday 7 October, roughly 51 nautical miles north of Madinat ash Shamal, Qatar. UKMTO reported casualties on board without giving a number. The security firm Ambrey reported a fire, which the crew extinguished, and "multiple casualties"; other accounts put the injuries as minor.
Acers is a 51,400 dwt MR2 chemical and products tanker. Equasis lists the owner as Valvoria Shipping, registered in Türkiye, and the ship manager as the Greek firm Med & Baltic Shipmanagement. The security firm Marisks said three drones hit the ship while she was drifting. Ambrey said she had begun moving towards Kuwait under her own power. Her AIS track showed an inbound passage through the US-designated southern route of the Strait of Hormuz on the night of 3 to 4 October.
Why does the location matter?
Since late September the attacks have concentrated on the Strait of Hormuz itself, where at least 12 tankers have been struck since 29 September. Martin Kelly of EOS Risk Group said Acers is the first Iranian strike on a ship inside the Gulf away from Hormuz since 9 September. On that day the bunker tanker Hercules Star was hit at anchor 24 nautical miles northwest of Port Rashid in the UAE, killing two seafarers, and the VLCC New Andros was struck 28 nautical miles southeast of Al-Faw, Iraq.
The Joint Maritime Information Center rates the threat in the Strait of Hormuz as severe and in the Arabian Gulf and Gulf of Oman as moderate. Clearwater Dynamics, a Pole Star Global subsidiary, said the strike raises the prospect of a wider combat area that would take in Qatar, Bahrain, Saudi Arabia, Kuwait and Iraq. Jakob Larsen, chief safety and security officer at BIMCO, said the recent attacks "seem to have dampened the appetite of shipowners to sail through the Strait".
Separately, satellite fire data showed a thermal anomaly about 30 nautical miles east of Fujairah in the Gulf of Oman, consistent with a vessel fire. No ship had been identified by the time of writing.
What happened in the Red Sea?
Early on 7 October a small craft fired shots at the Singapore-flagged containership CUL Klang in the southern Red Sea, north of Bab el-Mandeb. The Maritime Security Centre Indian Ocean said the crew were unharmed, the craft withdrew and the ship continued northbound. The 2024-built ship is operated by China's CUL Lines, and her AIS message stated Chinese ownership and a Chinese crew. No group claimed the attack, and small boats in the area are also known to approach ships to protect fishing nets.
