United Nations, May 14 (IANS): UN Secretary-General Antonio Guterres condoled the death of a UN Department of Safety and Security (DSS) staff member and injury to another DSS staffer in an attack in Gaza, said his Deputy Spokesman.

The incident occurred on Monday morning when their UN-marked vehicle was struck as they were on their way to the European Hospital in Rafah, said Farhan Haq, the Deputy Spokesman.

"The Secretary-General condemns all attacks on UN personnel and calls for a full investigation. He sends his condolences to the family of the fallen staff member," he added as quoted by Xinhua news agency report.

With the conflict in Gaza continuing to take a heavy toll -- not only on civilians but also on humanitarian workers -- the Secretary-General reiterates his urgent appeal for an immediate humanitarian cease-fire and the release of all hostages, said Haq.

The DSS staffer became the first international staff member of the United Nations killed in Gaza since October 7, 2023. Nearly 190 Palestinian UN staffers have lost their lives.

The names and nationalities of the DSS staffers killed and injured were being withheld as the United Nations was in the process of informing the relevant governments and the relevant family members, the Deputy Spokesman added.

He said the world body is trying to get details of the incident.

The DSS staffers were doing their regular work of going to different locations to assess security conditions, he said.
