Unidentified gunmen on Sunday blasted a pipeline for transporting crude oil in the Yemeni southeastern governorate of Shabwa.
The armed men attacked the pipeline pumping oil in Imad area of Habban district, said local sources.
A violent blast was heard from the subversive act whose results are still unknown, the sources added.
Last March, oil pipeline was blasted by unidentified gunmen at kilo 127 in al-Rawdha district, east of Ataq, the provincial capital of Shabwa.
In February, two pipelines were attacked, one in Habban district and the other in Jardan district, in the same governorate.
Frequent subversive attacks on crude pipelines in Shabwa cause heavy losses to a country already exhausted by a 5-year-old war.
Local authorities loyal to the UN-recognized government accuse gunmen, affiliated to the Emirati-backed Southern Transitional Council, of blasting the pipelines.
