The disaster relief organization World Central Kitchen said seven of its workers were killed in the Gaza Strip late on Monday in an Israeli strike on their convoy. It said one of the seven was a dual citizen of the United States and Canada, while the others were from Australia, Britain, Gaza and Poland. Here’s what is known about the victims, listed by homeland:

Australia

Australia’s foreign minister, Penny Wong, condemned the strike and named its citizen who had been killed as Lalzawmi Frankcom, known as Zomi.

“The tributes flowing for Lalzawmi ‘Zomi’ Frankcom tell the story of a life dedicated to the service of others, including her fellow Australians during natural disasters,” Ms. Wong said on social media, adding that “her tireless work to improve the lives of others should never have cost Ms. Frankcom her own.”

Last month, World Central Kitchen posted a video of Ms. Frankcom talking to a chef in the organization’s kitchen in Deir al Balah in central Gaza as he prepared rice and stew for hungry Gazans.

Britain

Britain’s foreign secretary, David Cameron, said on social media on Tuesday that “British nationals are reported to have been killed” in the incident. He gave no further details.

Gaza

A Palestinian working as a driver and translator for World Central Kitchen was also killed. Agence France-Presse and Reuters, which gave two different names for the man, released photos of his body being carried at his funeral in Rafah, in southern Gaza.

Poland

Damian Sobol, an aid worker from the southeastern Polish city of Przemysl, died in the attack, according to the city’s mayor, Wojciech Bakun.

“There are no words to describe what people who knew this fantastic boy feel at this moment,” he said in a post on social media.

United States and Canada

Information about the identity of the dual citizen of the United States and Canada was yet to emerge.
