Israel says UN aid workers killed in school strike were Hamas members

Israel is defending its strike on a UN school turned shelter in central Gaza and says that the six UN aid workers among the 18 killed were members of Hamas. US Secretary of State Antony Blinken said he will raise the issue of protecting humanitarian sites with Israel, at the same time criticizing the US-designated terror group for 'hiding in' civilian sites. White House Bureau Chief Patsy Widakuswara has this report.
