One week ago, US President Donald Trump was given a hero's welcome in Israel after securing the Gaza ceasefire and exchange of Israeli hostages for Palestinian prisoners.
But the days since have shown just how precarious the ceasefire is, and Sunday brought its biggest test so far.
The Israel Defense Forces (IDF) launched a series of deadly strikes across Gaza, after two soldiers were killed in an attack it blamed on Hamas. An Israeli security official announced the suspension of aid deliveries.
It appears US pressure ensured the truce was not derailed and that Israel's crossings with Gaza reopened on Monday. Now it is clear mediators must stay closely involved to shore up the deal and settle key issues on the future of Gaza and Hamas.
Already, the president's special envoys Steve Witkoff and Jared Kushner are back in the region while Hamas negotiators are meeting Egyptian mediators and Palestinian factions in Cairo.
