Officials on the ground in Gaza say that at least 12 of the people killed were women. The Israeli army denied it struck the area.
Two days after an Israeli air strike on another camp stirred global condemnation, Gaza emergency services said four tank shells hit a cluster of tents in Al-Mawasi on Tuesday local time — a coastal area that Israel had advised civilians in Rafah to move to for safety.
At least 12 of the dead were women, according to medical officials in Gaza.
The Hamas-run health ministry said at least 64 others were injured.
The Israeli army denied it struck the area.
