The claim is mostly true because multiple reliable sources confirm that Hamas has resumed executing people in Gaza streets amid internal crackdowns, and Israel has responded by restricting aid to Gaza, raising concerns about the stability of the ceasefire.
Hamas is back to executing people in the streets of Gaza while Israel is cutting off aid again to the enclave, sparking fears the ceasefire could fall apart.

Key Evidence
Multiple sources including CNN and CBC News confirm public executions by Hamas in Gaza streets.
Israel has officially reduced aid shipments to Gaza due to ceasefire violations by Hamas, as reported by The Times of Israel and Globalnews.ca.
Media outlets like AFR and Reuters highlight fears that these developments threaten the ceasefire's stability.
What the Evidence Shows
Recent reports from a variety of reputable news organizations indicate that Hamas fighters have been publicly executing individuals in Gaza, often described as collaborators or rival faction members, as part of a violent crackdown to maintain control. Videos and eyewitness accounts documented by CNN, CBC News, and India Today show armed Hamas members carrying out executions in public spaces. Concurrently, Israel has announced reductions in humanitarian aid deliveries to Gaza, citing Hamas violations of ceasefire terms, particularly related to the handling of hostage bodies.
The Times of Israel and Globalnews.ca report that Israel is allowing only half the previously agreed number of aid trucks into Gaza. This combination of Hamas's internal violence and Israel's aid restrictions has led analysts and media outlets like AFR and Reuters to express fears that the ceasefire brokered with U.S. Involvement is fragile and at risk of collapse.
However, some progress was noted with Hamas handing over additional hostage bodies to Israel, which could be seen as a partial compliance step. Overall, the situation remains tense and fluid, with both sides taking actions that undermine the ceasefire's durability.
