A ceremony for seven aid workers of the World Central Kitchen killed by an Israeli strike in Gaza was held in Washington, AFP reports.

The founder of the US-based charity, Spanish-American chef Jose Andres, attended the interdenominational “celebration of life” at the National Cathedral in the US capital.

“They risked everything to feed people they did not know,” Andres said at the ceremony attended by Doug Emhoff, the husband of US Vice President Kamala Harris.

American cellist Yo-Yo Ma was expected to perform at the ceremony.

In a broken voice, Andres paid tribute to the seven volunteers — three Britons, a US-Canadian dual national, a Pole, an Australian and a Palestinian.
