"Extremist settlers, by targeting and killing Palestinian civilians, are undermining security and stability for both Israelis and Palestinians," Cameron said on social media site X, formerly known as Twitter.
"Israel must take stronger action to stop settler violence and hold the perpetrators accountable. We are banning those responsible for settler violence from entering the U.K. to make sure our country cannot be a home for people who commit these intimidating acts."
Earlier this week European Union foreign policy chief Josep Borrell said he would propose sanctions against Jewish settlers responsible for violence against Palestinians in the Israeli-occupied West Bank.
