An Indian sailor is missing after an attack on a commercial shipping vessel in the Strait of Hormuz area on Saturday.

The Cyprus-flagged GFS Galaxy was attacked off Oman’s northern coast while transiting the Strait of Hormuz as the shaky ceasefire between Iran and the US unravelled. Search operations are continuing for the missing sailor, while 23 crew members were rescued and given medical aid.

“Of the 11 Indian nationals on board, ten have been rescued so far, while one Indian National is reportedly missing,” India’s Foreign Ministry said in a statement. New Delhi condemned the attack, saying the targeting of civilian shipping and infrastructure in the region must end.

In June, three Indian sailors died when US forces enforcing a naval blockade of Iran fired on their vessel, the MT Settebello.

The deaths led to domestic pressure on the Modi government to raise the issue with the Trump administration, with India twice summoning US Chargé d’Affaires Jason Meeks to the Foreign Ministry in New Delhi.

The GFS Galaxy, a container ship, issued a distress call after it was hit, which reportedly happened about 44 nautical miles off Musandam Governorate, Oman’s Maritime Security Center said in a social media post on Sunday.

The UK Maritime Trade Operation had earlier reported a fire on board a container ship. Authorities later said the crew abandoned the vessel and evacuated into a lifeboat.

India’s Foreign Ministry spokesperson termed the continued attacks on commercial shipping in the region “worrisome.” The ministry said New Delhi is coordinating with Omani authorities on the search and rescue operation.

The US on Sunday said it carried out fresh waves of attacks on Iranian targets in retaliation for Tehran’s strikes on a commercial ship in the Strait of Hormuz.

Iran responded with a barrage of airstrikes targeting several countries in the Middle East, including Bahrain, Kuwait, Qatar, Oman, and Jordan.
