Iran resumed natural gas exports to Turkey on Thursday after a week-long halt following an explosion on the pipeline, the Iranian Oil Ministry's website, SHANA, reported on Friday.
"The export of gas to Turkey, halted due to explosion, was resumed at 14:26 local time (0956 GMT) on Thursday," Retuers quoted SHANA as reporting a National Iranian Gas Company spokesperson as saying.
It is not clear what had caused the blast which occurred in the eastern Turkish province of Agri but sabotage is common on pipelines between Iran, Turkey and Iraq, where Kurdish rebels operate.
Iran is Turkey's second-biggest supplier of natural gas after Russia, sending 10 billion cubic meters of gas each year. Turkey uses gas to fire half of its power plants.
Late last month, gas exports from Iran to Turkey were briefly halted due to a blast. The pipeline was swiftly repaired and gas flows were resumed a day later.
