The United States on Tuesday urged an impartial investigation into an Israeli strike in the Gaza Strip that killed seven staff of U.S.-based charity World Central Kitchen, saying Israel should do more to protect civilians. 

"We've spoken directly to the Israeli government about this particular incident. We've urged a swift, a thorough and impartial investigation," Blinken told reporters at a press conference in Paris. "What we have impressed upon the Israelis is to do more to protect innocent civilian lives, be they innocent Palestinian children or aid workers."

Speaking alongside Blinken, French Minister for Europe and Foreign Affairs Stephane Sejourne expressed France's "firm condemnation" of the Israeli airstrike. "Nothing can justify such a tragedy," he said.
