Israel's parliament, the Knesset, has passed a law allowing for the deportation of relatives of attackers who had advance knowledge of an act of terrorism or expressed support for it. The law has raised concerns that it specifically targets Palestinian citizens of Israel. Critics argue that it is unlikely to be used against Jewish Israeli citizens. About 20% of the country's population are Palestinian citizens of Israel, and some have been convicted for posting support or sympathy for Hamas on social media. The legislation is expected to face legal challenges.
