SANAA, Yemen, Dec. 19 (UPI) -- Yemeni investigators concluded that saboteurs used artillery rockets to attack a natural gas pipeline in a southern province last weekend.
Energy company Yemen LNG said this week that a 38-inch natural gas pipeline tied to the Balhaf terminal on the Gulf of Aden was attacked. Investigators said militants used two artillery rockets to detonate the pipeline, the Yemen Post reports.
The attack took place early Sunday about 100 miles north of Balhaf in southeastern Shabwa province.
The Yemeni news report notes two oil pipelines in the country are still out of service following attacks early this year. It said government authorities were negotiating with area tribes to give engineers access to the sites for pipeline repairs.
The report stated that the government believes acts of sabotage on energy infrastructure resulted in $500 million in lost revenue since March.
Separatist ambitions and a lingering al-Qaida presence in Yemen have complicated political transition in the country.
Yemen LNG last reported an attack on one of its pipelines in October.
