Yemen's Houthis in military exercises near Saudi border - tribal sources
The drill in al-Buqa area, which lies in the Houthis' home province of Saada, involves using different kinds of weaponry, including heavy weapons acquired from the Yemeni army, the sources said.
Saudi Arabia, the world's top oil exporter, regards the Iranian-backed Shi'ite group which seized control of the Yemeni capital Sanaa in September as a terrorist group. In 2009, Riyadh carried out a military operation including air raids against the Houthis after a number of cross-border incursions.
