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.

Palestinians and Israelis have been shaken by the latest breakdown. From the start of the war, I was with him 24 hours a day, I never left him, bereaved father, Shadi Abu Obeid told the BBC in Khan Younis as he fought back tears at the funeral of his 14-year-old son Mohammed early on Monday.

At least 45 Palestinians were killed, local hospitals report, with deadly strikes targeting areas purportedly linked to Hamas operations. However, civilian casualties, including children, have also been reported.

Tough rhetoric and domestic pressure on Netanyahu are anticipated as Israel's parliament begins its winter session, and an internal election looms within the prime minister's Likud party. The path to lasting peace remains riddled with challenges, necessitating careful diplomatic navigation.
