An Israeli air strike on a school in Gaza City has killed at least 22 Palestinians, mostly women and children, according to Gaza's Hamas-run health ministry.
The school, closed during the war, was housing displaced people, the health ministry said.
The Israel Defense Forces (IDF) said it targeted a Hamas command centre which Israel said the militant group was using to "plan and carry out terrorist attacks”.
Hamas has denied using schools and other civilian sites for military purposes.
The Hamas-run government media office said the people killed in Saturday's strike in the al-Zaytoun area included several children and six women.
Gaza's civil defence agency reported the same death toll and added that one of the women was pregnant.
