The armed group attacked the pipeline in the Wadi Abida area of Marib, the local government officials told AFP.
"Oil flow came to a near complete halt," said one official, speaking on condition of anonymity.The same group late on Monday sabotaged Marib's power lines, leaving the province in "total darkness" and bring the gas plant services to a halt, another official said.
The pipeline that runs 320 kilometres (200 miles) from Safer oilfields in the east to the export terminal in the western Hudaydah province frequently comes under attack in the Wadi Abida area.
The last such act of sabotage occurred on April 8. In December, the army launched an offensive against tribesmen suspected of being behind the attacks, sparking clashes that left 17 people dead.
