UK Foreign Secretary David Lammy has announced that Britain has paused free trade talks with Israel, summoned its ambassador, and announced further sanctions against West Bank settlers.
Lammy said the offensive was not the way to bring remaining hostages home, called for Israel to end the blockade of aid and condemned what he called "extremism" in some sections of Israel's government.
Britain also sanctioned a number of individuals and groups in the West Bank who it said had been linked with acts of violence against Palestinians.
Prime Minister Keir Starmer added that he was horrified by the military escalation in Gaza.
