Israel says two male Israeli hostages have been rescued in Rafah, as Israeli air strikes hit the southern Gazan city.
The Israeli military says Fernando Simon Marman, 60, and Louis Har, 70, are in "good medical condition".
Israel says there was "aerial coverage and a wave of strikes" to accompany the hostage raid.
One official from the Hamas-run health ministry says 48 Palestinians were killed in the strikes, another says it's "about 100".
It follows warnings from the international community over Israel's planned offensive in the city, where 1.5 million people are sheltering.
Israel launched its operations in Gaza after more than 1,200 people were killed on 7 October by Hamas, who also took 253 people hostage.
The Hamas-run health ministry in Gaza says more than 28,100 Palestinians have been killed and more than 67,500 injured since then.
