**The Saudi-Houthi ceasefire failed and the US-Yemen truce stayed in force through Oct. 31.**

On Sunday, Saudi Arabia and the Houthi movement said their ceasefire negotiations had collapsed. No ceasefire agreement had been announced by October 31. No effective ceasefire was in place by that date. At the same time, the United States and Yemen's recognized government kept their ceasefire in force through October 31.

The US-Yemen truce had been confirmed on Saturday, the day before the Saudi-Houthi talks ended. The continuation of that ceasefire covered the entire month of October.

The collapse left fighting between Saudi forces and Houthi fighters ongoing. Neither side reported a reduction in attacks after the failed talks. The lack of an agreement meant no cessation of hostilities was achieved.

With the Saudi-Houthi ceasefire absent, the US-Yemen truce continued to be the sole active ceasefire in the region. The persistence of that truce provided a limited channel for humanitarian aid.

## Analysis

The failure of the Saudi-Houthi ceasefire attempts means that combat operations along the Red Sea corridor are likely to persist, extending civilian exposure to airstrikes and naval blockades. Without a binding pause, reconstruction and aid delivery remain constrained, and diplomatic momentum in Riyadh-Sanaa talks appears stalled.

The continued US-Yemen truce through the end of October offers a narrow window for humanitarian agencies to operate in previously inaccessible areas. Its maintenance suggests that the parties involved have upheld at least a minimal level of coordination, which could help mitigate the worst effects of the broader conflict, though the scale of relief remains limited.

This divergence may influence future negotiations, as stakeholders could leverage the US-Yemen truce as a model or pressure point, but the overall trajectory remains uncertain given the unresolved Saudi-Houthi hostilities.
