A pipeline that carries gas from Egypt to Israel was attacked for the sixth time in less than a year.
Three men fired on the pipeline at a pumping station in the northern Sinai on Tuesday morning, according to reports. The pipeline, which also serves Jordan then exploded.
It was not immediately known what affect the explosion would have on gas supplies to Israel and Jordan. Israel has not been receiving gas from Egypt since the pipeline was last attacked in July.
Egypt supplies Israel with more than 40 percent of its natural gas needs to produce electricity; electricity prices have risen by more than 10 percent in Israel since the attacks began.
The first attack on the pipeline came in February during the uprisings against deposed Egyptian President Hosni Mubarak. In July, machine-gun toting men overtook guards before blowing up a station in the Sinai.
Selling gas to Israel has been unpopular on the Egyptian street since the opening of the pipeline in 2008. Mubarak has been accused of giving Israel a sweetheart deal on the gas, since Egypt lost more than $714 million on the pact.
