Israeli air strikes on residential blocks in south Gaza killed at least 32 Palestinians, medics have said after Israel again warned civilians to relocate as it turns to attack Hamas in the enclave’s south after subduing the north, Reuters reports.

Such a move could compel hundreds of thousands of Palestinians who fled south from the Israeli assault on Gaza City to move again, along with residents of Khan Younis — a city of more than 400,000 — worsening a dire humanitarian crisis.
