After members of the Palestinian militant group Hamas launched a surprise attack into southern Israel on Oct. 7, killing about 1,200 people and taking some 250 others hostage, Tony Lo Giudice felt that he had to do something, and he decided to go to Israel to work as a volunteer.

Lo Giudice, who is Jewish, said he was among many Jews from around the world who heard the call to come and help Israel in any way they could.
