The US ambassador to Israel on Saturday accused ally Britain's government of antisemitism after its top diplomat described the situation in Gaza as "horrific". "The Brits have lost it. The Jew hate of their government knows no boundaries and knows no facts," Ambassador Mike Huckabee wrote on X of remarks by Foreign Secretary Ed Miliband, the son of Jewish refugees to Britain. While President Donald Trump has often criticized allies, such loaded remarks by a US official are unusual against Britain, among the closest US allies, said AFP. Miliband posted a video in which he described a meeting on Gaza and said that the British government had to take action. "Frankly, it was horrific what is unfolding. You know, the stories that people were telling me of medicines being blocked, children dying while waiting for vital life-saving equipment," Miliband said in the video. The Israeli foreign ministry accused him of ignoring facts and "making a video for a political audience". The Israeli foreign ministry said that 22,500 tons of medical supplies entered the Gaza Strip since a US-brokered ceasefire in October 2025, which has reduced but not ended the violence with Israel routinely striking what it says are Hamas targets. The UN humanitarian chief, Tom Fletcher, said in June that while more aid has been entering Gaza, it was not enough, with Israel restricting goods it says could have dual use -- including, at times, prosthetic limbs, he said. Aid groups say Israel's restrictions on engine oil and spare parts have also made it difficult to operate hospitals and other medical infrastructure. British Prime Minister Andy Burnham, who took office in July, has said his predecessor Keir Starmer was too soft on Israel. His government has said it is planning measures in response to rising attacks against Palestinians by Israeli settlers in the occupied West Bank, a move that Israel says will trigger retaliation.
