At least 100 people have travelled from the UK to Israel to serve in the IDF and fight Hamas after Saturday's terror attack.
The Israeli Embassy in the UK said it was understood those who travelled were "reservists and active-duty soldiers" in the Israel Defence Forces (IDF).
A statement said: "The Embassy of Israel understands that at least 100 reservists and active-duty soldiers have gone back to Israel from the UK to serve in the IDF".
The news comes as a 20-year-old British man serving in the IDF was killed in Saturday’s attack by Hamas terrorists.
Nathanel Young was killed on the Gaza border. Corporal Young was a soldier in the 13th Battalion, according to the IDF.
Young, a former pupil at JFS Jewish school in Kenton, had been living in the Bayit Shel Benji lone-soldier house in Raanana. He had moved to Israel from London.
Nathanel’s brother, Eliot Young, told the BBC: "Nathanel was full of life and the life of the party. He loved his family and friends and was loved by everyone.
"He loved music and was a talented DJ, DJing both on base and at Benji's House, the lone soldier house where he was living."
