Ahlul Bayt News Agency - Like most Islamic State (IS, former ISIS/ISIL) videos, the 9-minute-long clip was professionally shot and edited - with CGs and catchy background music.
It showed around two dozen IS fighters in full military gear training in the desert area, which is claimed to be located near the Yemeni capital, Sanaa.
The fake jihadist carried AK-47s, heavy machine guns and RPGs and then fired from some of their weapons.
After that, the apparent commander of the group stuck the black IS flag into the sand and pronounced that the “soldiers of the Caliphate" have arrived in Yemen to “cut the throats” of the Houthis.
"We have come to Yemen, with men hungry for your blood to avenge the Sunnis (Wahhabis and Salafis) and take back the land they have occupied," the IS commander said in a video, the International Business Times reported.
He then addressed all able-bodied anti-Shia men in Yemen to join him the battle against the Houthis.
In the end they face the camera and the man at the forefront sends his greetings to Abu Bakr al-Baghdadi, the self-declared caliph of the so-called “Islamic State”.
The fighter and several others direct their threats to the Houthi Shiites movement, who have been fighting the Yemen Al-Qaeda for years.
The so-called Islamic State has declared its official presence in war-torn Yemen as the fake jihadists posted a video online, threating to “cut the throats” of Shiite Houthi fighters.
The video was posted online on Friday, a day after a newly-announced division of the IS, the Green Brigade, claimed responsibility for a deadly attack on the Shiite rebels.
On Wednesday, five Houthi members were killed in the car bombing in Ibb province in central Yemen.
It became the second attack claimed by the IS in the country after 142 people were killed and another 350 injured in a series of suicide bombings at Shia mosques in Sanaa on March 20.
The Wahhabi IS and Al-Qaeda, which has traditionally been the dominant jihadist group in Yemen, view the Shiite Houthis as heretics.
Saudi Arabia started its military aggression against Yemen on March 26 - without a UN mandate - in a bid to restore power to the country’s fugitive former president, Abd Rabbuh Mansur Hadi, who is a close ally of Riyadh.
According to reports, nearly 1,000 people have been killed during the aggression.
