DEIR AL-BALAH, Gaza Strip (AP) — Israeli warplanes have struck two urban refugee camps in central Gaza. Saturday’s bombardment came hours after the Biden administration approved a new emergency weapons sale to Israel. The approval that bypassed Congress was granted despite international cease-fire calls over mounting civilian deaths, hunger and mass displacement in the enclave. Meanwhile, aid officials say condition in Gaza have only worsened a week after a U.N. Security Council call for the unhindered delivery of aid across the besieged territory. The World Health Organization says the spread of diseases including respiratory infections and diarrhea is intensifying amid repeated mass displacement.
