Seven Irish activists detained after Israel intercepts Gaza aid flotilla in international waters

Seven Irish citizens detained by Israeli forces; two activists held as hostages; hundreds of others seized during flotilla interception.
Israel has no jurisdiction in international waters. It's an act of piracy.
A flotilla participant describes the interception over 1,000 nautical miles from Gaza as unprecedented and unlawful.

In the ancient waters of the Mediterranean, far beyond any contested shore, a humanitarian flotilla carrying aid for Gaza was intercepted by Israeli naval forces — a moment that raises enduring questions about the reach of military power, the meaning of international law, and the lengths to which ordinary people will go to bear witness to suffering. Seven Irish citizens were detained and later handed to Greek authorities, while two others remained in Israeli custody. European leaders condemned the seizure as unlawful, but the deeper unease among those aboard was not merely legal: it was the recognition that when a state acts beyond its jurisdiction without consequence, the boundaries that protect all of us quietly erode.

  • Israeli naval forces boarded and seized flotilla vessels over 1,000 nautical miles from Gaza — a distance that stunned even seasoned activists who had never seen an interception so far into international waters.
  • Radio signals were jammed, drones circled overhead, and a surreal loop of pop music bled through the static as Israeli ships methodically picked off boats one by one in the darkness off Crete.
  • Seven Irish citizens were detained and held in uncertainty for hours before being transferred to Greek authorities, while two activists — Saif Abukeshek and Thiago Ávila — remained in Israeli custody, described by organisers as hostages.
  • Ireland's Taoiseach, Spain's prime minister, and Italy's prime minister all condemned the seizure as unlawful, demanding the release of their nationals and challenging Israel's claim to jurisdiction in international waters.
  • Flotilla participants warn the interception is not an isolated act but a precedent — that a military power willing to seize unarmed humanitarian vessels in European waters once will face little to stop it from doing so again.

On Wednesday night, Israeli naval forces boarded and seized vessels from the Global Sumud Flotilla in international waters off the coast of Crete — more than a thousand nautical miles from Gaza. Seven Irish citizens were among those detained, later handed to Greek authorities by Thursday morning. Two other activists, Saif Abukeshek and Thiago Ávila, remained in Israeli custody, described by flotilla organisers as hostages.

The flotilla had left Barcelona on April 12th with the aim of delivering humanitarian aid to Gaza and challenging the Israeli blockade. Those aboard described Israeli forces ramming and boarding vessels without warning, with radio signals jammed and drones overhead. Margaret Connolly, sister of President Catherine Connolly, was on a boat that managed to escape, accelerating away as a vessel just ten metres beside her was boarded. "We have no weapons, we're on our way to open a humanitarian pathway to Gaza," she told The Irish Times. "We have done nothing wrong."

Rachel McNicholl, wife of detained 74-year-old Fiacc O'Brolchain, spent hours without direct word from her husband, receiving updates only through the Department of Foreign Affairs. O'Brolchain had not planned to sail all the way to Gaza — he had intended to help prepare the boats and return home. Documentary filmmaker Jamie Goldrick, aboard an observer vessel, watched through CCTV feeds as Israeli ships worked through the flotilla methodically. "It was almost like a game of Pac-Man," he said.

What unsettled many was the sheer distance from Gaza. Veteran activist Cormac O'Daly noted that Israeli forces had previously intercepted aid ships around 150 nautical miles from their destination. This seizure, deep in European waters, represented a dramatic escalation. "Israel has no jurisdiction in international waters," he said. "It's an act of piracy."

Ireland's Taoiseach Micheál Martin, Spain's Pedro Sánchez, and Italy's Giorgia Meloni all condemned the action as unlawful. But for those who had been aboard, the concern ran deeper than diplomacy. If a military power could seize unarmed vessels in international waters without consequence, the precedent it sets reaches far beyond this flotilla — and far beyond Gaza.

On Wednesday night, in the dark waters of the Mediterranean more than a thousand nautical miles from Gaza, Israeli naval forces boarded and seized vessels from the Global Sumud Flotilla. Seven Irish citizens were among those detained. By Thursday morning, those seven had been handed over to Greek authorities—but two other activists, identified as Saif Abukeshek and Thiago Ávila, remained in Israeli custody, described by flotilla organisers as hostages.

The flotilla had departed Barcelona on April 12th with a straightforward mission: to deliver humanitarian aid to Palestinians in Gaza and challenge the Israeli blockade. The boats were in international waters off the coast of Crete when the interception occurred. According to those aboard, Israeli forces rammed and boarded the vessels without warning. The seven Irish detainees were named as Catriona Graham, Fiacc O'Brolchain, Robert Murphy, Colm Byrne, Martin Guilfoyle, Michael Fix, and John Connellan. They had been travelling alongside roughly 700 others across 58 vessels in the flotilla; 22 boats were ultimately detained.

Margaret Connolly, sister of President Catherine Connolly, was aboard one of the boats that escaped. She described the moment the Israeli ship appeared: a light approaching rapidly across the water, drones overhead, the sudden knowledge among the crew that this was an Israeli interception. She had gone below deck to gather passports and medicine bags. By the time she returned topside, it was over. Her boat accelerated away—"like the hammers of hell," she said—leaving a neighbouring vessel just ten metres away to face the boarding alone. She and her companions made it to safety, though she declined to say where. "We were 70 miles off the coast of Crete, in Mediterranean waters, international waters," she told The Irish Times. "We have no weapons, we're on our way to open a humanitarian pathway to Gaza, there's starvation and a siege on, we have done nothing wrong."

Rachel McNicholl, wife of the detained 74-year-old Fiacc O'Brolchain, had not heard directly from her husband since Wednesday afternoon. She received updates only through the Department of Foreign Affairs, which initially could not confirm whether the detainees would be taken to Israel or released. The uncertainty lasted until Thursday morning, when word came that the seven Irish citizens would be handed to Greek authorities instead. O'Brolchain had not originally planned to travel all the way to Gaza; he had intended to help prepare the boats and train the crew, then return home.

Jamie Goldrick, a documentary filmmaker aboard the Shireen, an independent observer vessel, watched the interception unfold in real time. A group chat with roughly 700 people across all the flotilla boats erupted with alerts. Radio signals jammed. Then, oddly, pop songs began bleeding through the static—"Blue (Da Ba Dee)" by Eiffel 65. Goldrick rushed below deck to upload footage to the cloud. Through CCTV feeds on the boat's starlink connection, he could see Israeli vessels boarding ships methodically, one after another. "It was almost like a game of Pac-Man," he said. "The Israelis were picking off the boats one by one and arresting them."

What struck many aboard as unprecedented was the distance from Gaza—over 1,000 nautical miles. Cormac O'Daly, a web developer from Vienna who had sailed on the Viva Palestina convoy to Gaza in 2009, said Israeli forces typically intercept aid ships about 150 nautical miles from their destination. This interception, far into international waters off Greece, represented a dramatic escalation. O'Daly's cabin had been packed with rice, pasta, flour, beans, medical supplies, and prosthetics for children who had lost limbs. "It's a crime and European governments need to do something about this," he said. "Israel has no jurisdiction in international waters. For them to attack us off the coast of Crete within international waters, it's an act of piracy."

Ireland's Taoiseach Micheál Martin condemned the seizure, saying it was unacceptable and that Israel must abide by international law. Spain's prime minister Pedro Sánchez and Italy's Giorgia Meloni both described the action as unlawful and called for the release of their nationals. Yet the concern among flotilla participants was not merely diplomatic. Mikey Cullen, a poet and secondary school teacher from Beaumont, warned that the interception set a dangerous precedent. "It shouldn't take Irish citizens being kidnapped in Europe to realise how rogue and lawless Israel is," he said. The fear was that if a military power could seize vessels in international waters with impunity once, nothing would prevent it from doing so again.

We were 70 miles off the coast of Crete, in Mediterranean waters, international waters. We have no weapons, we're on our way to open a humanitarian pathway to Gaza, there's starvation and a siege on, we have done nothing wrong.

Why did the Israeli forces go so far from Gaza to intercept these boats? That's over a thousand nautical miles.

Model

That's the question everyone's asking. Historically, they've intercepted aid ships much closer to Gaza—around 150 nautical miles out. This time they went all the way to international waters off Crete. It suggests either a deliberate show of force or a calculation that they could operate anywhere without consequence.

Inventor

And the two men still being held—Abukeshek and Ávila—why weren't they handed to Greece like the others?

Model

The flotilla organisers called them hostages, which suggests they're being held for a different reason. Maybe leverage, maybe they're being taken to Israel for interrogation. No one seems to know for certain. That uncertainty is part of what's frightening people.

Inventor

Margaret Connolly's boat escaped. What made the difference?

Model

Luck, mostly. She was on deck when the Israeli ship appeared. Her boat accelerated away while a neighbouring vessel ten metres away was boarded. She said they didn't know why the Israelis didn't pursue them. If they had, she'd be detained too.

Inventor

The pop songs coming through the radio—was that intentional jamming?

Model

It appears so. When radio signals jam, sometimes other broadcasts bleed through. It's disorienting, which may have been the point. It cut off communication between boats at a critical moment.

Inventor

What are people most worried about now?

Model

That this becomes normal. If Israel can seize ships in international waters off Greece without facing real consequences, what stops them from doing it again? And with two activists still unaccounted for, there's genuine fear about what happens next.
