Yemen LNG Co. said Wednesday the country's only liquefied natural gas pipeline supplying its plants was hit by an explosion late Tuesday, which the company said was due to sabotage.

The attack, the seventh in a year, hit the 38 inch gas pipeline that links block 18 to the Balhaf terminal on the Gulf of Aden, the company said in a statement posted on its website.

It occurred at 2200 hours local time Tuesday, 295 kilometers north of Balhaf.

The latest explosion comes only a few weeks after the plants resumed operation following sabotage in September. It wasn't immediately clear if the plants would be shut down following the latest incident or if exports were being halted.

The 320-kilometer LNG terminal has been repeatedly attacked by suspected al Qaeda-linked militants.

Yemen began exporting LNG from Balhaf in 2009. French group Total SA (TOT) has an almost 40% interest in the liquefaction plants.

The $4.5 billion Yemen LNG project has two production trains with a combined capacity of 6.7 million tons a year, supplying mainly to Asia, Europe, North America and South America.
