Gaza humanitarian aid delivery restarted on Monday, as the fragile ceasefire resumed with Israel, a day after the fragile deal faced its first major flareup.

Israeli forces launched a wave of deadly strikes, saying Hamas militants had killed two soldiers, and an Israeli security official said the transfer of aid into the territory was halted.

The military later said it resumed enforcing the ceasefire, and the official confirmed that aid deliveries would resume Monday. The official spoke on condition of anonymity because he’s not authorized to discuss the issue with the media.

Footage by the Associated Press showed aid trucks driving through the rubble in Gaza's southern city of Khan Younis.

They included other necessities such as fuel.

Palestinians, including women and children, queued outside a distribution centre in Khan Younis to receive boxes.

There is a concern among Palestinians about how much aid Israel is letting into Gaza, a key part of the agreement.

Raafat al-Qarra, a Khan Younis resident, told the Associated Press that the aid boxes he received ,contained meagre portions.

"It's not enough for anything, it's only enough for four or five days for a family of six people," he said.

He wished that aid packages were bigger or delivered more frequently.

"You can see how expensive prices are becoming, and we cannot afford to buy anything," he added.

The next stages of the ceasefire are expected to focus on disarming Hamas, Israeli withdrawal from additional areas it controls in Gaza, and future governance of the devastated territory.

The U.S. plan proposes the establishment of an internationally backed authority.

The Israel-Hamas war has killed more than 68,000 Palestinians, according to Gaza's Health Ministry, which doesn’t distinguish between civilians and combatants in its count.

The ministry maintains detailed casualty records that are seen as generally reliable by U.N. agencies and independent experts. Israel has disputed them without providing its own toll.

Thousands more people are missing, according to the Red Cross.

Hamas-led militants killed around 1,200 people, mostly civilians, and abducted 251 people in the attack that sparked the war.
