Israeli air strikes on residential blocks in south Gaza killed at least 47 Palestinians on Saturday, medics said, after Israel again warned civilians to relocate as it girds for an onslaught against Hamas in the enclave’s south after subduing the north.

According to Reuters, overnight on Saturday, 26 Palestinians were killed and 23 wounded by an air strike on two apartments in a multi-storey block in a busy residential district of Khan Younis, according to health officials.

A few kilometres to the north, six Palestinians were killed when a house was bombed from the air in the town of Deir Al-Balah, according to health authorities.

A third Israeli air strike on Saturday afternoon killed 15 Palestinians in a house west of Khan Younis, close to a shelter for displaced people, witnesses and medics said.
