There was a big natural gas leak at Shams 4 farm of the Petroleum Company on road 77 from Matrouh-Siwa yesterday, according to eyewitnesses. They said there was an explosive cloud above the well. One of the active labor leaders assured there was a high state of emergency, where all cars and heat sources that could lead to ignition were removed from the area. The 400 meter farm area was evacuated and a fire truck was ready. Workers were banned around the area but only for severe necessity of security.
