“There is no concept that could explain or excuse the brutality that we have witnessed since October 7,” Erdogan said during a summit of Turkic States in the Kazakh capital Astana.
“To put it bluntly: crimes against humanity have been committed in Gaza for exactly 28 days,” he said.
“Our priority is to establish a humanitarian ceasefire quickly,” he said.
Israel has relentlessly bombarded Gaza since October 7.
The health ministry in Gaza strip has said 9,061 people have been killed during subsequent strikes in the Palestinian territory, including 3,760 children.
Israel has said it is not targeting civilians and that it is trying to rout out and destroy the Hamas militant group responsible for the October 7 attacks.
