Indonesian humanitarian activists have returned home following a week of uncertainty, violence, and psychological distress during a mission to deliver aid to Gaza. Among the returnees is 24-year-old Hendro Prasetyo, a member of the Islamic humanitarian group SMART 171, who stated that the experience has replaced his fear with a sense of outrage and determination.
The Flotilla Interception
The mission was part of the Global Sumud Flotilla (GSF), a convoy of approximately 50 vessels that departed from Turkey in mid-May. The objective was to deliver symbolic aid to the Palestinian exclave and draw global attention to the escalating humanitarian crisis.
On May 14, Hendro Prasetyo boarded the Kasr-1 after undergoing training to prepare for potential interception. However, on May 18, news spread via group chats that Israeli forces had begun intercepting vessels near Cyprus.
The Kasr-1 attempted to change course to avoid capture, but Israeli forces boarded the vessel on May 19. During the boarding, communication devices were confiscated and mobile phones were thrown into the sea, cutting the activists off from the outside world.
Allegations of Severe Mistreatment
Rather than being moved to formal detention facilities, hundreds of activists were reportedly rounded up and held in two shipping containers that had been converted into makeshift prisons. Detainees reported being subjected to physical violence, torture, and restricted access to food and water during their four days in custody.

Herman Budianto Sudarsono, an activist from the organization Dompet Dhuafa, described experiencing physical strikes to his neck and knees, as well as being electrocuted in the rib area. He also reported witnessing significant sexual abuse within his container.
“There were also many cases of sexual abuse, with around 52 assaults in my container, ranging in severity, including cases of rape,” Herman said.
The GSF reported that preliminary screening of all participants identified at least 15 cases of sexual assault, including rape, among the detainees. Overcrowding was also a major issue, with spaces designed for 12 people being forced to hold up to 30 detainees overnight.
Political Reaction and Official Responses
While Israeli authorities have denied all allegations of abuse, video footage released by National Security Minister Itamar Ben-Gvir has fueled international skepticism. The video, captioned “Welcome to Israel,” showed restrained detainees being taunted by officials.
The footage sparked widespread condemnation, leading some Israeli officials to distance themselves from the incident. Prime Minister Benjamin Netanyahu stated that the actions shown were “not in line with Israeli norms and values.”
Implications and Future Outlook
The return of the activists has highlighted a stark contrast between those on the flotilla and the more than 9,000 Palestinians currently in detention, who, according to Hendro Prasetyo, face daily torture without the guarantee of return.
The detailed testimonies from these participants could lead to increased international scrutiny of maritime interception tactics. The documented accounts of mistreatment may serve to strengthen the resolve of humanitarian groups planning future missions to the region.
