Yemen's Shia Houthi fighters are becoming a political and military force to be reckoned with.

The group was originally a small faction based in the northern town of Saada.

But now it is running a huge and heavily-armed rebellion taking over new territories in the south. They are strongly opposed to a proposed division of the country into six regions.
