An Israeli court has prolonged the detention of two activists from a Gaza-bound humanitarian aid flotilla, who were abducted by Israeli authorities last week, according to an Israeli rights group. The Ashkelon Magistrates’ Court granted the state's request to extend the detention of Saif Abu Keshek from Spain and Brazilian Thiago Avila until May 10. The pair were among dozens of activists sailing for Gaza as part of the Global Sumud Flotilla, intercepted by Israeli forces in international waters off Greece on April 30. Organizers say Abu Keshek and Avila were taken to Israel for questioning. Adalah stated that the court's decision validates the state's lawlessness and that it will appeal the decision. The extension was based on 'secret evidence' that Abu Keshek, Avila, and their lawyers couldn't review. No charges have been filed, but the men face accusations, including affiliation with a 'terrorist organization'. Lawyers for the activists argue the allegations are baseless. The activists remain in isolation, subjected to intense lighting and blindfolding. They continue a hunger strike since their abduction on April 30. The flotilla's organizers demand their release. Adalah lawyers visited the activists at Shikma Prison in Ashkelon, where they reported 'severe physical abuse amounting to torture'. The Global Sumud Flotilla's first voyage drew worldwide attention before Israeli forces intercepted the boats.
