CAIRO (Reuters) - Israeli tanks advanced to the edge of the Mawasi displaced persons' camp in the northwest of the southern Gaza city of Rafah on Sunday in fierce fighting with Hamas-led fighters, residents said.

Images of two Israeli tanks stationed on a hilltop overlooking the coastal area went viral on social media, but Reuters could not independently verify them.

"The fighting with the resistance has been intense. The occupation forces are overlooking the Mawasi area now, which forced families there to head for Khan Younis," said one resident, who asked not to be named, on a chat app.

More than eight months into Israel's war in the Hamas-administered Palestinian enclave, its advance is focused on the two areas its forces have yet to seize: Rafah on Gaza's southern tip and the area surrounding Deir al-Balah in the centre.

Residents said Israeli tanks had pushed deeper into western and northern Rafah in recent days, blowing up dozens of houses.

The Israeli military said it was continuing "intelligence-based, targeted operations" in the Rafah area and had located weapons stores and tunnel shafts, and killed Palestinian gunmen.

The armed wings of Hamas and the Islamic Jihad movement said their fighters had attacked Israeli forces in Rafah with anti-tank rockets and mortar bombs and pre-planted explosive devices.

Elsewhere, an Israeli airstrike killed eight Palestinians in Sabra, a suburb of Gaza City in the north, and another strike killed two people in Nuseirat in central Gaza.

The military said it had struck dozens of targets throughout the Strip.

On Saturday, Palestinian health officials said at least 40 Palestinians had been killed in separate Israeli strikes in some northern Gaza districts, where the Israeli army said it had attacked Hamas's military infrastructure. Hamas said the targets were the civilian population.

In Beit Lahiya in the northern Gaza Strip, health officials at Kamal Adwan Hospital said a baby had died of malnutrition, taking the the number of children dead of malnutrition or dehydration since Oct. 7 to at least 30, a number that health officials say reflects under-recording.

Israel's ground and air campaign in Gaza was triggered when Hamas-led militants stormed into southern Israel on Oct. 7, killing around 1,200 people and seizing more than 250 hostages, according to Israeli tallies.

The offensive has left Gaza in ruins, killed more than 37,400 people, according to Palestinian health authorities, and left nearly the entire population homeless and destitute.
