Brazil’s president called Israel’s continued detention of Brazilian Thiago Ávila and Spanish-Swedish national Saif Abu Keshek “a serious affront to international law.”
Brazilian President Luiz Inácio Lula da Silva on Tuesday condemned Israel’s twice-extended detention of two Global Sumud Flotilla members abducted last week off the coast of Greece while attempting to break the decadeslong Israeli blockade of Gaza and deliver humanitarian aid to its people amid an ongoing genocide.
“Maintaining the imprisonment of Brazilian citizen Thiago Ávila, a member of the Global Sumud Flotilla, is an unjustifiable action by the Israeli government, causes great concern, and must be condemned by all,” Lula said on X.
“The detention of the flotilla activists in international waters had already represented a serious affront to international law,” he added. “For this reason, our government, together with that of Spain, which also had a citizen detained, demands that they receive full guarantees of safety and be immediately released.”
pain’s government has also condemned Israel’s capture of Abu Keshek and demanded his immediate release, and like Lula, called the detention illegal because it occurred in international waters. Abu Keshek is also a citizen of Sweden, which has not condemned his detention—or even mentioned him by name—but has asked that “the rights of any Swedish citizens will be respected.”
Adalah Legal Center, the Palestinian group in Israel representing Ávila and Abu Keshek, said Tuesday that the Ashkelon Magistrates’ Court approved Israel’s request to extend the pair’s detention through May 10. This, after the court on Sunday prolonged their detention by two days.
“The court’s decision to extend the detention of humanitarian activists abducted in international waters amounts to judicial validation of the state’s lawlessness,” Adalah assertedad, vowing to appeal the decision, which the group said was based on “secret evidence.”
Adalah noted that “because the activists were abducted over 1,000 kilometers away from Gaza and are not Israeli citizens, Israeli domestic law does not apply to them.”
Israel contends that it is enforcing a lawful naval blockade of Gaza Strip, and that under the laws of naval warfare, that blockade can be enforced not only in its territorial waters, but also on the high seas.
Adalah said, “Crucially, the court granted the full six-day extension requested by the state without imposing any limitations or judicial constraints on the interrogation period,” adding that the stated purpose of their continued detention is further interrogation.
“Ávila reported being subjected to repeated interrogations lasting up to eight hours,” the group reported. “Interrogators have explicitly threatened him, stating he would either be ‘killed’ or ‘spend 100 years in jail.’”
“Both activists remain in total isolation, subjected to 24/7 high-intensity lighting in their cells, and kept blindfolded whenever they are moved, including during medical examinations,” Adalah said, accusing interrogators of “trying all the time to connect the humanitarian aid with Hamas to present it as a service to Hamas.”
Israel’s Ministry of Foreign Affairs claims that both men were affiliated with the Popular Conference for Palestinians Abroad, which the US government accuses of “clandestinely acting on behalf of” Hamas, the militant Palestinian resistance group that led the October 7, 2023 attack on Israel.
Still, no charges have been filed against the pair, who Adalah said have been on hunger strike since April 30 in protest of their detention.
Abu Keshek and Ávila were among the more than 170 Global Sumud Flotilla members intercepted and seized last week in international waters 45 nautical miles west of the Greek island Kythira and 600 nautical miles from Gaza in what many critics have called an act of piracy.
All of the other flotilla members have been released. Many said they brutally abused by their Israeli captors, who threatened to kill them. The Washington Post reported 34 people—including citizens of Australia, Colombia, Italy, Ukraine, and the United States—required medical attention for broken ribs, noses, and other injuries. Detained activists also said they were denied food and water, and were forced to sleep on deliberately flooded floors. Both Abu Keshek and Ávila had visible facial injuries during their first court appearances.
In a statement issued on Monday, Global Sumud Flotilla said Abu Keshek and Ávila “are being subjected to systemic psychological torture and explicit threats to the lives of their families.”
