Of the many factors that will determine the fate of the fragile ceasefire in Gaza, one of the most difficult to quantify and predict is the level of popular support for Hamas.

On Monday, Hamas threatened to delay the release of further Israeli hostages, accusing Israel of breaches of the ceasefire deal. The uncertainty, just over halfway into the ceasefire’s six-week first phase, complicates talks on the far more difficult second phase. It also jeopardises the pause in the devastating fighting and the increase in humanitarian aid for Gaza that the truce has made possible.

Saudi Arabia’s foreign ministry has rejected Israeli prime minister Benjamin Netanyahu’s remarks about displacing Palestinians from their land, Reuters reports.

Israeli officials have suggested the establishment of a Palestinian state on Saudi territory. Netanyahu appeared to be joking on Thursday when he responded to an interviewer on pro-Netanyahu Channel 14 who mistakenly said “Saudi state” instead of “Palestinian state”, before correcting himself.

Hours after the ceasefire was declared on Sunday, Hamas fighters were back on Gaza’s streets. Not many, it was true, and those who appeared were armed only with Kalashnikov rifles and some rudimentary body armour, but they were there.

In Khan Younis, a handful of pickup trucks with gunmen onboard drove through cheering crowds of young men. Dozens of uniformed fighters with Hamas headbands were visible when the three Israeli hostages were handed over in Gaza City. Elsewhere, there were reports that Hamas policemen, dressed in blue police uniform, deployed in some areas after months in hiding to avoid Israeli strikes.
