KHAN YOUNIS, Gaza Strip (AP) — Multiple airstrikes hit Gaza’s southern city of Khan Younis overnight into Thursday, killing more than 50 people in a second consecutive night of heavy bombing, while another airstrike in the north of the Palestinian territory left more than a dozen people dead, authorities said.

Asked by the BBC about the scale of Israeli attacks, Marco Rubio said the US was "troubled" by the humanitarian situation in Gaza.
