Gazans were fleeing their homes and rushing their dead and wounded to hospitals after fresh Israeli strikes on Friday, as combat resumed between Israel and Hamas.
Smoke billowed over the southern cities of Rafah and Khan Younis following Israeli strikes, with deaths recorded in both places, according to hospital officials and AFP journalists at the scene.
In Khan Younis, a group of men chanted "God is greatest" as they rushed through the streets carrying a body wrapped in a white shroud.
Sitting on a bed at the city's Nasser Hospital, Amal Abu Dagga wept, her beige veil covered in blood.
"I don't even know what happened to my children," she said.
A relative, Jamil Abu Dagga, told AFP the family had been at home when the bombs started falling.
"My house was destroyed, so was my neighbour's," he said from the Nasser hospital, his head bandaged.
Another member of the family, Anas Abu Dagga, 22, said the "war has returned, even more fierce".
In Rafah, a young man rushed a badly wounded child out of a refugee camp hit by an explosion, while others could be seen pulling a motionless person from the rubble.
Marwan al-Hams, the director of Al-Najar hospital in Rafah, where many Palestinians fled after being told by Israel to leave the north of the territory, said strikes had killed at least nine people in the city, including four children.
In the north of the Gaza Strip, the fireball from a large explosion could be seen from across the border in the Israeli city of Sderot, and an AFPTV livecam broadcast rolling clouds of grey smoke and the sounds of automatic gunfire within the first 90 minutes of the truce expiring.
Speaking from an unnamed hospital in Gaza, UNICEF spokesman James Elder said in a video posted to social media platform X on Friday that a bomb had landed "literally 50 metres away".
"I cannot overstate how much the capacity of hospitals has been reduced," he said. "We cannot see more children with the wounds of war, with the burns, with the shrapnel littering their body, with the broken bones."
"This is a war on children," he added.
