A convoy of trucks carrying aid passed through Khan Younis in Gaza on Sunday as a ceasefire between Israel and Palestinian militant group Hamas appeared to be holding.

According to the ceasefire agreement, humanitarian aid will be ramped up into Gaza, and permitted to travel freely between north and south of the enclave on the two main roads.

Israeli troops pulled back under the first phase of a US-brokered agreement reached this week to end the war, which has killed tens of thousands of people and left much of the enclave in ruins.

US President Donald Trump will join the leaders of more than 20 countries in Egypt on Monday for an international summit aimed at finalising permanent peace terms, a spokesperson for Egyptian President Abdel Fattah al-Sisi said. The summit will take place in the Red Sea resort city of Sharm el-Sheikh.

Hamas is expected to release its remaining Israeli hostages by noon on the same day, in accordance with the terms of the ceasefire.

Hundreds of trucks per day are expected to surge into Gaza carrying food and medical aid.

UNICEF spokesperson Tess Ingram said on Saturday the United Nations’ children’s agency expects to significantly scale up supplies of high-energy food for malnourished children, menstrual hygiene supplies, and tents, starting on Sunday.
