The rocket targeted the Khor Mor gas complex, owned by UAE energy company Dana Gas, said Sediq Mohammed, an official from the adjacent Qadr Qaram district.

"The rocket hit around 500 metres (yards) outside the complex," he said.

There was no immediate claim for the attack.

Counter-terrorism forces in Kurdistan's Sulaimaniyah province confirmed there had been no casualties or damage to the complex.

The gas field lies between the cities of Kirkuk and Sulaimaniyah.

Unclaimed Katyusha rocket attacks targeted the same complex on Wednesday and Friday, also without causing casualties or damage.

Energy infrastructure elsewhere in the autonomous Kurdish region has also come under attack in recent weeks.

In May, there was minor damage following a rocket attack at the Kawergosk refinery, northwest of the regional capital Arbil.

In April, three rockets hit near the same facility -- one of the largest in the area -- with no casualties or damage reported.
