Isis release new video announcing their arrival in Yemen and threatening Houthis

The Iraqi-based Islamic State (Isis) have released a new video announcing they are establishing a new arm in Yemen and warned the Shi'ite-inclined Houthi rebels.

Declaring their official presence in conflict-torn Yemen, the jihadists warned to "cut the throats" of the Houthis.

"We have come to Yemen, with men hungry for your blood to avenge the Sunnis and take back the land they have occupied," one of the militants who was donning a matching uniform along with other militants said in the footage.

The video was released after the local Yemeni group Green Brigade claimed the responsibility for an attack against Houthis in the central province of Ibb. Just like the earlier IS releases, the latest nine-minute video was professionally shot and edited.

In the recording, around two dozen AK-47-wielding jihadists were seen dressed in full military gear. The video was claimed to be shot in a desert area near the Yemeni capital Sana'a though it cannot be independently confirmed.

The jihadist in the video also addressed fellow Sunni men in the country to join the battle.

Yemen has been reeling under intense unrest for several weeks after Houthi rebels went on the offensive capturing several places. However, they were stopped in their advances by a Saudi-led military operation launched in co-operation with other Sunni regional states.
