The Global Sumud Flotilla of around 45 vessels began its voyage to Gaza last month. Israel said the activists would be deported to Europe, without specifying which countries they would be sent to. Unions have called for another strike on Friday to urge stronger action from the government against Israel’s actions in Gaza. Nelson Mandela’s grandsonSpain’s digital transformation minister, Oscar Lopez, had urged the flotilla not to cross into Israel’s declared exclusion zone, extending 150 nautical miles off Gaza. South Africa urged Israel to immediately release the activists, who include Mandla Mandela, the grandson of anti-apartheid hero Nelson Mandela.
