Israel’s far-right security minister posted video footage of himself taunting the most high-profile Palestinian prisoner while visiting him in jail this week, in an encounter that has prompted outrage from supporters.

A video widely circulated on Friday shows Israel’s far-right national security minister admonishing a Palestinian leader face-to-face inside a prison, saying Israel will confront anyone who acts against the country and “wipe them out.

President Donald Trump has said little about his idea of relocating many of the Gaza Strip’s 2 million Palestinians to other countries since he stunned the world by announcing it in February. Israel has been in talks with African countries — many of which are themselves wracked by war and at risk of famine — about taking Palestinians in.
