Portuguese activists deny admitting crimes after Israeli detention of Gaza aid flotilla

Four Portuguese activists landed in Madrid on Sunday evening, exhausted and vindicated. Mariana Mortágua, a left-wing parliamentarian, Sofia Aparício, Miguel Duarte, and Diogo Chaves had spent the previous four days in Israeli custody after their humanitarian flotilla was intercepted in international waters. As they prepared to board a flight home, Mortágua made a sharp clarification to reporters: they had never admitted to any crime, despite Israeli authorities' framing. "They invented a crime, but we never admitted it and we left the country," she said.

The four were part of the Global Sumud flotilla, an initiative that assembled more than forty vessels and five hundred volunteers from dozens of countries. The mission was straightforward—deliver humanitarian aid to Gaza's Palestinian population. On Wednesday night, Israeli naval forces intercepted most of the flotilla while it was still in international waters, approximately seventy nautical miles (roughly one hundred thirty kilometers) from the Gaza coast. The Portuguese activists were taken into custody along with the other participants. They were transported to Saharonim prison in the Negev desert, where they remained for at least forty-eight hours without food or water, according to accounts they later shared on social media.

The legality of what happened is contested. International law specialists and human rights bodies—including Amnesty International and the UN's Office of the High Commissioner for Human Rights—have questioned whether Israel's actions were lawful. The flotilla was operating in international waters, where freedom of navigation is ordinarily guaranteed. Francisco Pereira Coutinho, a professor of international public law at Universidade Nova de Lisboa, has acknowledged that wartime circumstances might complicate that principle, potentially justifying an interception. But even in conflict, international law requires that humanitarian aid be permitted to reach civilian populations. The UN declared a famine in Gaza months earlier, making the flotilla's purpose undeniably urgent.

Israeli officials claimed, without evidence, that the flotilla was coordinating with Hamas. Yet no searches of the vessels were conducted before the detentions were made—a fact that Pedro Braga de Carvalho, an international law specialist, suggests undermines the government's legal position. If no inspection took place, no contraband or proof of terrorist activity could have been discovered. The detentions, by this logic, appear to have been made without factual basis.

Thameen Al-Kheetan, the UN's spokesperson for human rights, was direct in his assessment. Speaking to Reuters on Thursday, he characterized the interception as reinforcing what he called an illegal blockade of Palestinian territory. He reminded Israel of its obligations as an occupying power: to ensure that food and medicine reach the population, either by providing them directly or by facilitating and permitting independent humanitarian programs to operate without obstruction. The flotilla represented exactly the kind of assistance that international law says must be allowed through.

The Portuguese government had assigned a diplomat to accompany the four activists throughout their detention and release, according to the Foreign Ministry. By Sunday evening, they were on their way home, their detention over but the questions it raised still hanging in the air—about what obligations occupying powers truly have, about the difference between security and blockade, and about whether humanitarian work itself has become criminalized.
