Israeli forces seized a Gaza-bound aid boat and detained Greta Thunberg and other activists who were on board early Monday, enforcing a longstanding blockade of the Palestinian territory that has been tightened during the Israel-Hamas war. The boat, accompanied by the Israeli navy, was spotted off southern Israel's coast on Monday evening on its way to the Ashdod port, according to an Associated Press journalist at the scene. The activists were expected to be held at a detention facility in the Israeli city of Ramle before being deported, according to Adalah, a legal rights group representing the activists.
