Harrowing photos show how a young Gazan girl has been reduced to skin and bone as starvation continues to grip the Palestinian enclave, while Israel calls for action to bring hostages home.

The disturbing images show the sickly thin nine-year-old Maryam Duvvas, who is currently receiving treatment at Patient Friends Association Hospital in Gaza City and is reportedly in critical condition due to severe malnutrition.

In the horrifying photographs, the schoolgirl can be seen being cradled by her mother as her spine and ribs visibly stick out from her starved body.

Other images show severely malnourished babies and adults as the Gaza Strip finds itself on the brink of famine due to Israel's ongoing airstrikes and aid blockade, according to the United Nations.

However, Israel has denied claims of mass starvation and has accused Hamas of stealing and hoarding aid.
