An international flotilla delivering aid to Gaza reported Wednesday that Israeli vessels approached and encircled two of its boats with "dangerous and intimidatory maneuvers," causing navigation and communication blackouts as the group neared the war-torn territory.
The mission's organizers said two Israeli "warships" had approached fast and encircled two of the flotilla's boats, Alma and Sirius. All navigation and communication devices went down in what one organizer on board, Thiago Avila, described in a press conference as a "cyberattack". The flotilla appeared to have recovered some communications. Israeli officials did not immediately respond to a request for comment.
The Global Sumud Flotilla consists of more than 40 civilian boats, carrying about 500 people, among them parliamentarians, lawyers and activists, including Swedish climate campaigner Greta Thunberg.
The mission is the latest sea-borne attempt to break Israel's blockade of the Palestinian enclave to deliver food and medicine. It is currently within 120 nautical miles (222.24 kilometers) of Gaza's coast, inside an area that Israel is policing to stop any boats approaching. It is expected to arrive Thursday morning if not intercepted.
"These hostile actions placed unarmed civilians from over 40 countries in grave danger," the flotilla said in a statement, adding that it will continue its course towards Gaza. It was not clear who operated the vessels that approached the flotilla.
A video post on the flotilla's Instagram page showed the silhouetted outline of what appeared to be a military vessel with a gun turret near the civilian boats. Reuters confirmed that the video was filmed from the vessel Sirius because its rigging and lines matched file imagery of the boat. Reuters could not confirm the identity of the other vessel in the video or when the video was taken.
The flotilla has raised tensions in recent days since it was attacked by drones, which dropped stun grenades and itching powder on the vessels, causing damage but no injuries. Israel did not comment on that attack, but has said it will use any means to prevent the boats from reaching Gaza, arguing that its naval blockade is legal as it battles Hamas in the coastal enclave.
Italy and Spain deployed naval ships to help with any rescue or humanitarian needs, but have said they will not engage militarily. Turkish drones have also reportedly followed the boats.
However, Italy and Spain said they would stop following the flotilla once it got within 150 nautical miles (278 kilometers) of Gaza for safety reasons.
At the press conference held by organizers Wednesday, Francesca Albanese, the top U.N. expert on Palestinian rights, said any interception of the flotilla "would be yet another violation of international law, the law of the sea" since Israel had no legal jurisdiction on waters off Gaza.
Israel has imposed a naval blockade on Gaza since Hamas took control of the coastal enclave in 2007 and there have been several previous attempts by activists to deliver aid to Gaza by sea, both during the latest conflict and others.
In 2010, nine people onboard the Turkish aid ship Mavi Marmara were killed after Israeli soldiers boarded a flotilla of six ships manned by 700 pro-Palestinian activists from 50 countries.
In June this year, Israeli naval forces detained Thunberg and 11 crew on a small ship organized by a pro-Palestinian group called the Freedom Flotilla Coalition as they approached Gaza.
Italy and Greece on Wednesday jointly called on Israel not to hurt the activists aboard and called on the flotilla to hand over the aid to the Catholic Church for indirect delivery to Gaza – a plea the flotilla has previously rejected.
