Activists from a Gaza-bound aid flotilla intercepted by Israeli naval forces are being held at an Israeli port before being transferred to prison, according to an Israeli rights group and the flotilla's organizers.
The flotilla was making a renewed attempt to deliver aid to war-shattered Gaza after earlier missions were also intercepted by Israel in international waters.
Video footage showed Israeli forces opening fire on at least two flotilla vessels Tuesday, with Israel saying those were warning shots.
Organizers say they aim to break Israel's blockade of Gaza by delivering humanitarian assistance, something aid bodies say is still in short supply despite a U.S.-brokered cease-fire in Israel's genocidal war on the Palestinian territory in place since October 2025 that includes guarantees of increased aid.
Activists aboard past flotillas that were intercepted by Israel were deported after being detained.
Ships from the flotilla had set sail for a third time Thursday from southern Türkiye.
Israel said all 430 activists on board the flotilla's boats had been transferred to Israeli vessels and that they would be allowed to meet their consular representatives after arriving in Israel. The flotilla's organizers say participants hailed from 40 countries, aboard 50 vessels.
Israel's Foreign Ministry said on X Monday that it "will not allow any breach of the lawful naval blockade on Gaza."
Israeli rights group Adalah said in a statement that the activists had been "detained at Ashdod port" and "taken into Israel against their will as Adalah attorneys entered for legal consultations."
The flotilla's organizers said in a statement that the activists would be taken to Ketziot prison in Israel's southern Negev desert. It said that Adalah lawyers would not be able to meet them until they get to Ketziot.
Without specifying how many Italian citizens were on board the flotilla, Italy's Foreign Ministry said they were "expected to be transferred to a facility for identification and then allowed to depart."
The ministry said Italians, including a member of parliament and a journalist, had been on board. Citizens of South Korea were also among those detained by Israeli naval forces, President Lee Jae Myung said Wednesday, calling Israel's actions "way out of line."
"What is the legal basis (for the arrests)? Is it Israeli territorial waters?" Lee questioned, adding, "Is that Israeli land? If there is conflict, can they seize and detain third-country vessels? Detaining our citizens for reasons not justified under international law is too excessive and inhumane."
Most of Gaza's more than 2 million people have been displaced, many now living in bombed-out homes and makeshift tents pitched on open ground, roadsides, or atop the ruins of destroyed buildings.
Israel, which controls all access to the Gaza Strip, denies withholding supplies for its residents. It has retained control of more than 60% of Gaza since a U.S.-backed cease-fire in October, with the Palestinian resistance group Hamas controlling a sliver of territory along the coast.
