Gas exports from Iraq's Khor Mor field, one of the largest in the Kurdistan region, resumed on Saturday after a drone attack on Wednesday that shut down production, sources told Reuters.
The sources said the exports that resumed were of liquefied petroleum gas and not the gas supplied from the field for regional power generation.
On Thursday, joint field operator Dana Gas said that a rocket hit a storage tank at the gas field, leading to a shutdown in production and extensive power cuts.
There was no immediate claim of responsibility and authorities did not say who was behind Wednesday's attack.
The attack was the most significant since a series of drone attacks in July hit oilfields and cut production from the region by around 150,000 barrels per day.
