Spanish national Saif Abu Keshek and Brazilian national Thiago Avila appeared before a court in Ashkelon for a second hearing, after being brought to Israel last week following the interception of their vessel by Israeli forces off the coast of Greece.“The court approved their detention until Sunday morning,” said Miriam Azem of Adalah, which is providing legal representation.

An AFP journalist witnessed the activists being escorted into the courtroom with their legs shackled.The two were among dozens of individuals aboard a flotilla that had set sail from France, Spain and Italy with the stated aim of delivering humanitarian supplies to Gaza and challenging Israel’s long-standing blockade.

Adalah said the activists have been on a hunger strike for six days and alleged that both were subjected to physical and psychological abuse in detention. The group said they were being held in isolation under constant high-intensity lighting, with Avila allegedly exposed to extremely cold temperatures.“They are kept blindfolded at all times whenever they are moved outside their cells, including during medical examinations,” the group said.

Israeli authorities have rejected the allegations.During an earlier hearing, prosecutors presented a list of charges including assisting the enemy during wartime and membership in, and providing services to, a terrorist organization, according to Adalah.

Defense lawyers challenged Israel’s jurisdiction, arguing the activists had been unlawfully detained in international waters.Israel’s foreign ministry said both individuals were affiliated with the Popular Conference for Palestinians Abroad, which it alleged has links to Hamas. It described Abu Keshek as a leading member and said Avila was also suspected of involvement in illegal activity.

The flotilla was part of the Global Sumud initiative, whose previous attempt last year was similarly intercepted. Israeli forces stopped the latest convoy early on Thursday off Greece’s coast.Israel has maintained a blockade on Gaza since 2007 and controls access points into the territory.

Aid flows have been severely disrupted during the ongoing war that began in October 2023, contributing to shortages of essential supplies.
