Live Updates: Israel says it killed two Hezbollah commanders in Lebanon; U.S. urges Israel to address 'catastrophic conditions' in Gaza

Israel should take urgent steps to address conditions in Gaza and allow “desperately needed” humanitarian aid to reach civilians, the U.S. Ambassador to the U.N. told the organization’s Security Council on Wednesday.

“Conditions are catastrophic and will further deteriorate if additional steps are not taken,” Linda Thomas-Greenfield said.

“We are particularly concerned that Palestinian civilians have nowhere safe to go,” she added. “That must change, and now.”

“The U.S. expects Palestinian civilians to be permitted to return home,” Thomas-Greenfield said. “There must be no demographic or territorial change in the Gaza Strip.”
