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.
