Gunmen blew up Yemen’s gas pipeline late on Monday the fourth attack this year, but Yemen LNG has not confirmed whether the output at the Balhaf LNG plant in Shabwa has been halted.
The company said in a statement the explosion occurred at 171 km north of the plant and there were no victims.
Al-Qaeda militants bombed the 38-inch natural gas pipeline, which links Block 18 in Marib to the Balhaf Liquefaction Plant in Shabwa, three times earlier this year, the latest in late April.
It was repaired and resumed pumping in May after losses estimated by the authorities at $400 million.
Yemen LNG has three long-term contracts with Suez LNG Trading, Total Gas and Power, and Kogas.

France's Total leads the Balhaf LNG project with a 39.62% share and its partners are Hunt, Yemen’s Gas Company and General Authority of Social Security and Pensions, South Korea's SK Energy and KOGAS and Hyundai (5.88%).
Oil and gas pipelines in Yemen have been repeatedly attacked in the past two years with militants and tribal saboteurs blamed.
The Marib oil pipeline resumed pumping in mid-July after nine-month halt on repeated attacks.
