An additional 171 activists detained by Israel for taking part in the Global Sumud Flotilla (GSF), an aid mission bound for Gaza, were deported from the country on Monday, said a statement issued by the Israeli Foreign Ministry.
According to the statement, the deportees are citizens of the United States and 18 European countries, including the Swedish climate campaigner Greta Thunberg.
The GSF, comprising dozens of vessels carrying more than 470 volunteers from over 40 countries, aimed to challenge Israel's naval blockade and deliver food and medical aid to Palestinians in Gaza.
Most of the flotilla's vessels were intercepted in the Mediterranean Sea by the Israeli Navy on Thursday morning, with the final ship being stopped the following day.
All passengers were transferred to the port of Ashdod in southern Israel, and 341 of them have been deported so far.
Several activists returning home have alleged abuse and humiliation by Israeli guards. Israel’s foreign ministry earlier described reports that detainees had been mistreated as "complete lies".
