Unknown assailants Tuesday blew up a gas pipeline that feeds Yemen 's liquefied natural gas to the Balhaf export terminal, a local official said, just days after it was repaired from previous sabotage.

A bomb planted underneath the pipe in Safir fields, in the
Marib Province , east of the capital San'a, exploded early Tuesday, the official said.

Yemen LNG said Saturday the pipeline had been repaired after a bomb put it out of service in August.
