Tribesmen blew up a crude pipeline linking Yemen's eastern Maarib province to its Red Sea coast, Al Arabiya TV said on Saturday.
Citing security sources, the channel said the incident took place on Saturday morning. Oil industry sources in Yemen said the pipeline was badly damaged and pumping had stopped.
The pipeline is the only channel transferring crude from Maarib to the Red Sea Terminal for export.
The channel said Yemeni forces were bombing the homes of tribesmen including Nasser Hammad al-Doham suspected of allegedly hiding al-Qaeda members.
It said there was a security cordon around an area that is home to the tribe of Hassan Abdullah Al Aqili, accused of assassinating two military officials this month.
Tribal leaders have given higher casualty tolls for the military operation, which was launched on Wednesday in the eastern Maarib province of Wadi Abeida.
