THE Indian Navy evacuated all 20 crew from a stricken vessel in the Red Sea, after a Houthi attack killed three seafarers, including two Filipinos, in the first civilian fatalities from the Yemeni group's campaign against the key shipping route, Reuters reports.

The Iran-aligned militants fired a missile at the Barbados-flagged, Greek-operated True Confidence about 50 nautical miles off the Port of Aden, setting it ablaze.

In a statement, the owners and manager said all 20 crew and three armed guards on board were taken to hospital in Djibouti in the Horn of Africa by an Indian warship.

Two of the dead were Filipino nationals, while the third was Vietnamese, the owners and managers said, expressing condolences to families. Two other Filipinos were also severely injured.

In a statement, Department of Foreign Affairs (DFA) Undersecretary Eduardo de Vega said that the department will assist the Filipino victims of the attack.

"The Philippine Embassy in Cairo, Egypt will send a team to Djibouti to provide all necessary assistance for these affected Filipinos," he said. "The Philippines remains committed to achieving a long-lasting resolution to the conflict."

In a message to Manila's GMA News Online, Mr De Vega said that the 13 surviving Filipinos have been brought to Djibouti, while the remains of the fatalities are still on board the ship. "They are being recovered," he said.

Images released by the Indian Navy showed a helicopter winching crew members from a small life raft in choppy seas and taking them to a naval ship.

Some wounded were shown lying in the bottom of a navy lifeboat sent to assist. They were carried on stretchers onto the ship and were shown later with heavily bandaged limbs as they were evacuated to the Djibouti hospital.

"The vessel is drifting well away from land and salvage arrangements are being made," the companies said in the statement.

The Houthis have kept up a relentless campaign of attacks on vessels in one of the world's busiest shipping lanes since November, in what they say is solidarity with the Palestinians during Israel's war with against Hamas in Gaza.

Stephen Cotton, of the International Transport Workers＊ Federation (ITF), the leading seafarers union, also called for better protection.

"No delivery window is worth the loss of seafarers' lives," he said. "We call on the industry to divert ships around the Cape of Good Hope until safe transit through the Red Sea can be guaranteed."

The True Confidence was sailing from China to Jeddah and Aqaba with a cargo of steel products and trucks.

The vessel is owned by Liberia-registered True Confidence Shipping SA and operated by Greece-based Third January Maritime. There is no current connection with any US entity, the companies said.
