The announcement comes after a series of strikes between the Houthis and the Saudi-led coalition in recent days. On Sunday, the Houthis claimed to have hit sites belonging to Saudi national oil company Aramco, saying the attack was retaliation for what they described as 50 Saudi-led coalition air and missile strikes in Yemen within 12 hours. Saudi Arabia has not yet commented on the Houthi claims.
The conflict escalated sharply in September, when the Houthis captured Yemen's entire Red Sea coastline, including the strategically vital Bab al-Mandab Strait. The seizure has further disrupted global oil supplies, as the strait is a key shipping lane for crude tankers.
Yemen's internationally recognized government, which has been based in Saudi Arabia since the Houthis seized the capital Sanaa in 2014, has now ordered a military operation to take back lost territory. The exact scope and timeline of the campaign have not been detailed, but it marks the most significant attempt to reverse Houthi gains in months.
