Russia on Tuesday criticised a decision by several countries to suspend their funding for the United Nations' Palestinian refugee agency, calling it a form of "collective punishment".
A number of donors including the United States announced they would halt funding to the UNRWA agency over Israel's accusations that some of its staff were involved in the October 7 Hamas attack.
"What has happened and is happening is collective punishment, prohibited by international humanitarian law," Russian Foreign Minister Sergei Lavrov said.
An investigation into accusations UNRWA staff were involved in the October 7 attack should not be replaced by "collective punishment" of the agency and Gazan people, he added.
"If that investigation is implemented, then the facts will be established," Lavrov said.
"But if the investigation is replaced by collective punishment of both UNRWA and, most importantly, those to whom the UN has provided invaluable assistance, then I think that is the wrong decision," he added.
The foreign minister was speaking at a press conference alongside his Gambian counterpart.
Israel's relentless military offensive since October 7 then has killed at least 26,751 people in Gaza, most of them women and children, according to the health ministry.
