Rescuers in the city of Rafah, southern Gaza, have pulled a baby girl alive from the rubble after an Israeli air strike. People used their hands to free Mariam Abu Akel from the debris, before a rescuer ran with her to a nearby hospital. Doctors there swabbed her cuts. The baby had been sheltering in a house with her family when the strike took place, which killed her mother and sister, Reuters reported. Her father and young brother survived. The air strike killed 20 people and injured 55, according to a Hamas-run health ministry spokesperson. More than 21,500 people - mostly children and women - have been killed during Israeli retaliatory attacks on Gaza, according to the Hamas-run health ministry. Thousands more are believed to be still under rubble of buildings destroyed by air and artillery strikes. Israel launched its military campaign in Gaza after Hamas attacked southern Israel on 7 October, killing about 1,200 people - most of them civilians - and taking about 240 hostages.
