The United Nations called Tuesday for “a clear, transparent and credible investigation” of mass graves uncovered at two major hospitals in war-torn Gaza that were raided by Israeli troops.

Credible investigators must have access to the sites, U.N. spokesman Stephane Dujarric told reporters, and added that more journalists need to be able to work safely in Gaza to report on the facts.

He called for independent and transparent investigations into the deaths, saying that “given the prevailing climate of impunity, this should include international investigators.”

Columbia University averted another confrontation between students and police early Wednesday, but the situation remained tense with campus officials saying it would continue talks with pro-Palestinian protesters for another 48 hours.

University President Minouche Shafik had set a midnight deadline to reach an agreement on clearing an encampment of protesters on campus but the school extended negotiations, saying it was making “important progress.” Student protesters had committed to dismantling and removing a significant number of tents, the New York Ivy League university said in a statement.

The Senate passed legislation Tuesday that would force TikTok’s China-based parent company to sell the social media platform under the threat of a ban, a contentious move by U.S. lawmakers that’s expected to face legal challenges and disrupt the lives of content creators who rely on the short-form video app for income. 

The TikTok legislation was included as part of a larger $95 billion package that provides foreign aid to Ukraine and Israel and was passed 79-18. It now goes to President Joe Biden, who said in a statement immediately after passage that he will sign it Wednesday.
