The Israeli Navy attacked three ships of the Gaza-bound Freedom Flotilla Coalition (FFC) early Wednesday in international waters roughly 120 nautical miles (222 kilometers) from the enclave.

"We confirm that three vessels -- Gaza Sunbird, Alaa Al-Najjar and Anas Al Sharif -- have been attacked and illegally intercepted by the Israeli military at 04:34 a.m., 220 km off the coast of Gaza," the International Committee for Breaking the Siege on Gaza said on the US social media company X’s platform.

"The video shows the moment of the attack on the Sunbird boat and the attempt to conceal the crime by striking the camera with a weapon," it added.

A livestream on the coalition’s YouTube channel showed several Israeli soldiers raiding the Gaza Sunbird.

Israel’s Channel 13 said earlier that the Israeli army was preparing to attack the flotilla.

“At roughly 120nm away from Gaza, Israel has attacked our flotilla,” the coalition said later on the US social media company Instagram’s platform.

Most livestreams have been disconnected, it added, highlighting that the Israeli military “is trying to divert their route. More to come.”

The coalition official tracker was also jammed.

"The Israeli military has no legal jurisdiction over international waters. Our flotilla poses no harm," said the coalition on Instagram.

The flotilla ships "carry vital aid worth over $110,000 USD in medicines, respiratory equipment, and nutritional supplies that were destined for Gaza’s starving hospitals. Tag your politicians and media - end Israel’s human rights abuses now," it said.

Around 100 people are on board the nine-boat convoy, part of the FFC’s “Thousand Madleens” mission to challenge the illegal Israeli siege on Gaza.

The FFC, established in 2010, has launched dozens of missions aimed at delivering aid and drawing global attention to the humanitarian crisis in the Israel-besieged Gaza Strip.

The latest convoy set sail after Israeli naval forces attacked and seized more than 40 boats sailing to Gaza last week to challenge the Israeli blockade and detained more than 450 activists on board.

Israel, as the occupying power, has previously attacked Gaza-bound ships, seized their cargo and deported the activists on board.

Israel has maintained a blockade on Gaza, home to nearly 2.4 million people, for nearly 18 years and further tightened the siege in March, when it closed border crossings and blocked food and medicine deliveries, pushing the enclave into famine.

Since October 2023, Israeli bombardments have killed more than 67,100 Palestinians in the enclave, most of them women and children, and rendered it uninhabitable.
