Egyptian prosecutors began investigations at the scene of an attack on a gas pipeline between Egypt and Jordan in Egypt's Sinai Peninsula Tuesday night.
Eyewitnesses living in Baghdad village in central Sinai had told Al-Ahram Arabic news website that they heard a large blast before midnight and saw flames from the pipeline shoot into the sky.
The gas pipeline which carried Egyptian natural gas to Israel and Jordan was been attacked 15 times by suspected Islamist militants.
Egypt halted gas exports to Israel in April 2012.
The attacks on the pipeline took place after the start of Egypt's revolution in January 2011 and lasted till the election of Islamist former president Mohamed Morsi in June 2012.
After Morsi's ouster by the armed forces following mass protests against him in June 2013, attacks on pipelines resumed, accompanied by an intensified militant campaign against the Egyptian army and police forces in Sinai.
