The head of the UN agency for Palestinian refugees (UNRWA) says Israel is inflicting “man-made” and “politically motivated starvation” on Gaza as the UN’s World Food Programme reports aid stocks in the enclave are completely depleted.

Michael Fakhri, UN rapporteur on the right to food, said Israel has blockaded Gaza for more than 50 days and continues “executing this starvation campaign with no repercussions”.

Medical sources tell Al Jazeera that at least 45 people were killed in Israeli attacks across Gaza since early on Friday and the daily death toll continues to mount.

At least 51,439 Palestinians have been confirmed killed and 117,416 wounded in Israel’s war on Gaza since it began 18 months ago.

The Gaza Government Media Office updated its death toll to more than 61,700, saying thousands of people missing under the rubble are presumed dead. At least 1,139 people were killed in Israel during the Hamas-led October 7, 2023, attacks and more than 200 were taken captive.

Rights group Defense for Children International – Palestine (DCI-P) has deplored the killing of a 16-year-old boy shot dead by Israeli forces while closing up the shop where he worked east of Nablus in the occupied West Bank.

The killing occurred when Israeli troops travelling in two military vehicles deployed in the occupied West Bank’s town of Salem on Thursday afternoon. Noticing the military presence, the victim, Abdulkhaleq Mosab Abdulkhaleq Jabour, decided to close up the small shop where he worked.

Moments later, he was shot in the chest while closing up and died of his injuries, DCI-P said, adding the Israeli troops who shot the teenager had “hid among some olive trees” close to the shop and had also impeded relatives from providing first aid.

“Abdulkhaleq was clearly no threat to Israeli soldiers, and yet they fatally shot him anyway, and as usual, no one will be held accountable for killing a Palestinian child in cold blood,” the organisation’s Ayed Abu Eqtaish said in a statement.

Israeli soldiers have now killed 24 Palestinian children in the occupied West Bank so far this year, the children’s rights group said.
