US Secretary of State Antony Blinken said on Friday that "far too many" Palestinians have died and more needs to be done to save lives and channel aid as Israel pursues a punishing offensive against Hamas in Gaza.His comments came after Prime Minister Benjamin Netanyahu agreed under US pressure to open up daily humanitarian pauses, while vowing no let-up of Israel’s offensive until Gaza is “demilitarised, deradicalised and rebuilt”.In London, Rishi Sunak's spokeswoman told reporters: “We've consistently called for humanitarian pauses to allow aid in and hostages out, and welcome the announcement of four-hour pauses … as a first step.” Mr Blinken said in New Delhi that Washington "appreciates" Israeli steps to minimise civilian casualties but that was not enough, with "far too many" Palestinians still being killed.
