SANAA - Assailants blew up Yemen's main oil export pipeline, halting crude flows, local officials said on Wednesday, while other gunmen attacked electricity lines, causing a power outage in most of the country's northern cities.
There was no immediate claim of responsibility, but Yemeni tribesmen often attack oil pipelines and power lines. Al Qaeda-linked militants have also carried out such attacks.
The attacks late on Tuesday and early on Wednesday coincided with an offensive by Yemeni government forces in mountainous areas of southern Yemen that led to the capture of the militants' main stronghold in that region.
The oil pipeline was bombed twice in less than 12 hours late on Tuesday in an area between the central Maarib province and the capital Sanaa, the local officials said, an area that has suffered numerous attacks since 2011.
