TEL AVIV, Israel (AP) — Drones attacked a vessel carrying aid to Gaza on Friday in international waters off Malta, the group organizing the shipment said, in the latest confrontation over efforts to send assistance to the Palestinian territory devastated by nearly 19 months of war.

A nearby tugboat responded to a distress call from the Conscience, which authorities said experienced a fire that was brought under control. The vessel was carrying 12 crew members and four civilians, the Maltese government said, adding that those aboard refused to leave the ship. The group was safe and no serious injuries were reported, it said.

The Freedom Flotilla Coalition accused Israel of attacking its ship. The group did not provide evidence for that claim or to show that the fire was caused by drones, but in a video it shared an explosion could be heard. Another video showed a fire blazing.

The Israeli army did not respond to a request for comment. Israel has cut off Gaza from all imports, including food and medicine, since the beginning of March, leading to what is believed to be the worst humanitarian crisis in the war with Hamas, the Palestinian militant group.

Explosions in the night

Mecid Bagcivan, an activist from Turkey who was aboard the Conscience, was getting ready for bed when two explosions rocked the ship about two minutes apart, he said. At first it seemed there had been a collision. Then the crew saw fire and realized it was an attack, Bagcivan told The Associated Press.

As the crew radioed Malta for help, Bagcivan said someone impersonated them on the same channel saying help was no longer needed. Those on board scrambled to fight the fire on their own, leaving some with minor injuries, he said. Help later arrived, and after hours the fire was extinguished.

The ship was trying to reenter Maltese waters amid fears of a second attack, according to a statement from the crew.

“We feel like right now we’re safe, but we don’t know what Israel is going to do,” Bagcivan said. “We can’t trust no one in this situation after we get bombed in the middle of the night.”

Stranded in international waters

Video taken after the explosions showed two large holes in the ship’s deck, with thick smoke surrounding the vessel. The person recording the footage said the ship had been hit twice and was on fire about 14 miles from Malta. The video was provided by Codepink, a grassroots peace and social justice movement.

The ship’s generator was badly damaged and will need to be repaired before continuing, said Charlie Andreasson, who has been involved with the Freedom Flotilla for more than a decade.

It’s unclear where the ship will be able to stop for repairs, said Tighe Barry, a Codepink member who was among a group of activists who took speedboats to the Conscience after the attack. The boats were turned away by Maltese authorities, he said, but one person made it aboard and spoke to the captain.

Barry said the nation of Palau revoked its flag from the Conscience prior to the attack, and authorities in Malta, Greece and Turkey have threatened to confiscate the ship if it comes to port. Barry said the ship is loaded with medicine and food supplies.

“To get a new flag will take months, so they’re just stuck out there,” Barry said of the crew.

Conflict over Israel’s blockade

Israel says the blockade is an attempt to pressure Hamas to release hostages it took during the Oct. 7, 2023, attack that triggered the conflict. Hamas-led militants assaulted southern Israel that day, killing some 1,200 people, mostly civilians, and abducting 251. Hamas is still holding 59 hostages, 24 of whom are believed to be alive.

In response, Israel launched an offensive that has killed over 52,000 Palestinians, mostly women and children, according to Gaza’s Health Ministry, which does not distinguish between fighters and civilians. Israel’s bombardment and ground operations have destroyed vast areas of the territory and left most of its population homeless.

When an aid flotilla attempted to break a blockade of Gaza in 2010, Israeli forces stormed a Turkish ship, the Mavi Marmara, killing nine people on board.

On Friday, the Conscience was hit about 16 miles (26 kilometers) from Malta, according to the Freedom Flotilla.

Photos provided by Cypriot authorities showed the ship with damage to its side.

Ship sailed from Tunisia on route to Gaza

According to the ship-monitoring website Marine Traffic, the Conscience left the Tunisian port of Bizerte on Tuesday and arrived Thursday morning in the area where it reported being attacked.

Volunteers who had traveled to Malta were meant to board the ship to go to Gaza, the group said. Andreasson said climate activist Greta Thunberg was supposed to have participated. The organization said Thunberg did not board and was safe.

The ship’s 12 crew members are from Turkey and Azerbaijan, said Medea Benjamin, co-founder of Codepink.

Turkey condemned the attack and pledged to hold the perpetrators accountable.

The assault “threatens freedom of navigation and maritime security in international waters,” Turkish Foreign Ministry Spokesman Oncu Keceli said in a statement posted on the X social media platform.

The attack happened as aid groups have warned that the humanitarian response in Gaza is on the verge of collapse.

The International Committee of the Red Cross said Friday that it will not have access to food, medicine and life-saving supplies needed for many of its Gaza programs if aid deliveries don’t resume immediately.

Programs at risk include “common kitchens” that often give residents the only meal they receive each day and could be forced to halt operations in a few weeks, the ICRC said.

“Aid must be allowed to enter Gaza. Hostages must be released. Civilians must be protected,” the committee said. “Without immediate action, Gaza will descend further into chaos that humanitarian efforts will not be able to mitigate.”
