Speaking from Jerusalem, Mladenov said the fragile ceasefire brokered in October 2025 is now in acute danger of unraveling entirely. He cited recent Israeli airstrikes on what the military described as Hamas rocket-launching positions and a series of cross-border incursions by armed groups from Gaza as key drivers of the escalation.
'We are witnessing a steady erosion of the understandings that stopped the fighting last year,' Mladenov told reporters. 'If this ceasefire collapses, it will be a point of no return. The cost of another war would be catastrophic for civilians on both sides and would set back any prospect of a political horizon for years.'
The envoy's remarks come after a week of rising tensions along the Gaza border, including the killing of two Israeli soldiers by a sniper and retaliatory strikes that killed at least five Palestinians, among them a senior Islamic Jihad commander. Israel has accused Hamas of failing to prevent attacks by other armed factions, while Hamas has blamed Israel for not fulfilling commitments to ease the blockade and facilitate reconstruction projects.
Mladenov's warning echoes previous UN statements but carries added weight as the current truce was seen as a rare diplomatic achievement following the 2024-2025 war. The ceasefire never formally included a mechanism for enforcement, and both sides have traded blame for its gradual breakdown.
International mediators, including Egypt and Qatar, have intensified shuttle diplomacy in recent days but have so far failed to broker a de-escalation. The United States has called on both parties to exercise restraint, while the European Union has warned that a return to full-scale hostilities would destabilise the entire region.
For now, the ceasefire technically remains in place, but Mladenov's 'point of no return' language signals that the UN considers the situation far more precarious than at any point since the truce was signed. The coming days will be critical in determining whether diplomatic efforts can prevent a full-scale relapse into war.
