Unknown militants attacked late Thursday the natural gas pipeline running between the capital Cairo and the Suez Canal city of Ismailia putting it a blaze, a security source told Anadolu Agency.
The source, who declined to be named, said the militants opened heavy machine gunfire at the pipeline.
"Firefighters rushed to the place and brought the fire under control, but closed down the pipeline," added the source.
He added that an explosive charge was found three kilometers from the site of the attacks.
"It has been defused."
The source said the aim of the attack was to disrupt natural gas supplies to the three Suez Canal cities of Ismailia, Suez and Port Said as well as the Sinai Peninsula.
No group has claimed responsibility for the attack until the filing of the story.
