A record 383 aid workers were killed in global hotspots in 2024, nearly half of them in Gaza during the warbetween Israel and Hamas, the U.N. humanitarian office said Tuesday on the annual day honoring the thousands of people who step into crises to help others, Associated Press reported.

U.N. humanitarian chief Tom Fletcher said the record number of killings must be a wake-up call to protect civilians caught in conflict and all those trying to help them.

“Attacks on this scale, with zero accountability, are a shameful indictment of international inaction and apathy,” Fletcher said in a statement on World Humanitarian Day. “As the humanitarian community, we demand — again — that those with power and influence act for humanity, protect civilians and aid workers and hold perpetrators to account.”

The Aid Worker Security Database, which has compiled reports since 1997, said the number of killings rose from 293 in 2023 to 383 in 2024, including over 180 in Gaza, according to Associated Press.
