Yemeni rebels, operating in the north of the country, have posted a video of their leader Abdul-Malik al-Houthi, showing him in apparent good health.
Officials in Yemen had claimed Mr Houthi had been seriously injured in December and had appointed a successor.
Fighting between the rebels from the minority Shia Zaidi sect and the Yemeni government has occurred sporadically since 2004.
The rebels are also in conflict with neighboring Saudi Arabia. BBC
