The Houthi advance comes amid rising tensions with Saudi Arabia, which leads a military coalition backing the internationally recognized government. On Sunday, clashes were reported across several frontlines, with the militia launching concentrated attacks aimed at breaking through government defenses and seizing new ground.
The fighting underscores a significant escalation in the Yemen conflict, which has been in a military stalemate for years. The Houthis, who control the capital Sanaa and much of the country's northwest, have recently stepped up operations as peace efforts have stalled.
Saudi-backed government forces have reportedly been caught off guard by the scale and intensity of the Houthi offensive, which appears designed to redraw frontlines before any potential renewed diplomatic push. It remains unclear how far the Houthis intend to advance or whether they are seeking to capture major urban centers.
The United Nations and international observers have repeatedly warned that further escalation risks deepening one of the world's worst humanitarian crises. Yemen's infrastructure has been devastated by years of conflict, and millions face severe food and medical shortages.
The situation is fluid, with both sides claiming advances and reporting heavy casualties. There has been no immediate comment from the Saudi-led coalition on the latest developments.
