US fires Hellfire missiles at cargo vessel breaking Iran blockade

Strike on the Vela Nova

A US Navy helicopter fired two Hellfire missiles at the Panama-flagged cargo vessel Vela Nova in the Gulf of Oman on Tuesday, after the ship attempted to sail toward an Iranian port in violation of the American naval blockade. US Central Command (CENTCOM) said the attack targeted the ship's engine room and disabled its steering gear, alleging the crew had "ignored repeated warnings from American forces." The Austrian source identified the helicopter as an MH-60. The incident occurred before dawn, roughly 71 nautical miles (about 130 km) from the coast of Pakistan, as the vessel sailed westward through the Gulf of Oman.

Maritime security firm Vanguard provided an initial assessment of the strike.

All 17 crew members were accounted for and safe, Vanguard said. No casualties were reported, though the ship appeared to attempt transferring its crew to another civilian vessel after the strike, according to a US official cited by the Wall Street Journal. The UK Maritime Trade Operations (UKMTO) had earlier reported an incident in the Gulf of Oman involving a container ship and forces, without naming a country.

Blockade enforcement record

CENTCOM stated that throughout its blockade of Iranian ports, US forces have disabled 55 commercial vessels, disabled three "non-compliant vessels," and boarded two. The US reimposed its naval blockade of Iranian ports in mid-July, after a ceasefire tied to a June Memorandum of Understanding (MoU) between the US and Iran collapsed. The blockade aims to deny Tehran revenue from oil exports, with ships barred from approaching or departing Iranian ports. The MoU had been intended to launch renewed negotiations on a lasting peace, the future of sanctions on Iran, and its nuclear programme, and included a preliminary plan for a $300bn fund. Both the blockade and Iran's control over the Strait of Hormuz had been lifted as part of the June agreement.

Diplomatic stalemate

Efforts to return to an agreement have yielded little progress. On Monday, Trump called for reparations from Iran for "50 years" of damage. Tehran has previously called for reconstruction funding to be part of any deal. Iran has focused its diplomatic efforts on direct talks with Oman to determine new shipping lines in the Strait of Hormuz, through which 20 percent of the world's maritime fossil fuel trade transited prior to the war launched by the US and Israel on February 28. The conflict has been further complicated by attacks from Yemen-based Houthis on ships in the Bab al-Mandeb Strait, another key trade route in the region.

Prior casualties and escalation pattern

In June, three Indian sailors were killed during a US operation enforcing the blockade, according to an Indian official. Those were the first reported fatalities in the American effort to deny Iran oil export revenue and pressure Tehran into a deal. The blockade enforcement campaign has led to repeated incidents of ships being fired upon or forced to change course. The latest attack on the Vela Nova follows a 13-day escalation in July, with attacks mostly paused since then.
