CAIRO - An explosion went off Saturday morning at a gas compressor station in Egypt's northern Sinai Peninsula, triggering a huge fire along the gas pipeline, Egyptian media and witnesses said. Egypt's official TV said the explosion was the result of an attack, but provided no further details. The report could not be confirmed independently. The blast went off at a gas compressor station near the Sinai town of el-Arish, several hundred yards (meters) away from the local airport, witnesses said. From the compressor station, gas pipelines run to Jordan and Israel. El-Arish is about 44 miles (70 kilometres) from the Gaza Strip.
