At least 23 people have been killed and around 50 injured in an Israeli airstrike on a residential building in Gaza City, according to Palestinians. Medics said the attack on Wednesday hit homes in the Shejaiya neighbourhood,

Authorities in Hamas-ruled Gaza accuse Israeli forces of a "heinous massacre" with a strike on a school they say killed almost 30 people, many of them children.

Israeli strikes have killed more than a dozen people in the Gaza Strip as Israel sends more ground troops into the Palestinian territory to ramp up its offensive against Hamas.
