The first British nationals have left Gaza and crossed the Rafah border into Egypt, the Foreign Office has said.
UK teams are on the ground providing assistance, but the Foreign Office did not specify how many Britons had crossed the border.
A total of 76 wounded people and their companions left Gaza in ambulances today, according to a spokesman for the Palestinian Crossings Authority.
Around six buses carrying 335 foreign nationals also departed into Egypt, the spokesman added.
The Rafah border will be open again on Thursday to allow foreign passport holders out of Gaza, the authority confirmed.
Foreign Secretary James Cleverly said the crossing of the first British nationals was a “hugely important first step”.
He said the UK is working with Egyptian and Israeli authorities to ensure the crossing stays open, so all Britons can get out to safety in the coming days.
But there are still foreign nationals struggling to leave.
A UK-based academic and her five children were unable to leave Gaza for Egypt as the first group of injured evacuees moved over the Rafah border.
Dr Emilee Rauschenberger, 42, told Sky News that her family came to the border as they got notice from the UK’s Foreign Office that the crossing might be opening.
She said the family wanted to travel back to Manchester, having traveled to Gaza to visit her husband’s family three weeks ago.
“We want to leave Gaza and go back to Britain,” she said. “A few days after the war started we had to leave our homes and move to Khan Younis. We have been displaced the whole time.”
