Six British people have been killed in the Israel-Hamas conflict, the prime minister has said.
A further 10 are missing, he added.
Rishi Sunak made the announcement while addressing MPs in the House of Commons.
“We call for the immediate release of all hostages and I say to them: we stand with you… we stand with Israel,” he said.
“The murdered and the missing come from over 30 countries, including the United Kingdom.
“The terrible nature of these attacks means it is proving difficult to identify many of the deceased but with a heavy heart I can inform the House that at least six British citizens were killed.
“A further 10 are missing, some of whom are feared to be among the dead.”
He said eight flights evacuating more than 500 people had departed Israel so far.
“We mourn the loss of every innocent life,” he said, adding more than 1,300 people had been killed in the Hamas attacks and a further 2,600 Palestinians had been killed in Gaza.
While the UK has expressed its support for Israel, Mr Sunak said he would continue to call on the country to “take every possible precaution” to avoid harming civilians.
He also said the UK was working to prevent the conflict escalating and had increased aid to Palestinians by a third – an additional £10m.
Labour leader Sir Keir Starmer responded to his statement, saying it was important to speak with one voice in support for Israel.
He said an “acute humanitarian crisis” was unfolding and “civilians must not be targeted”.
