Sharjah 24 – AFP: Six rockets landed Sunday in northern Iraq's autonomous Kurdistan region, Kurdish counter-terrorism forces said, with "minor damage" reported at a key oil refinery, according to a separate security source.

"Six rockets fell near the Zab river in the Khabat district," Kurdish counter-terrorism forces said in a statement, without specifying the target of the attack.

The attack caused no casualties or damage, the statement said.

But two sources speaking on condition of anonymity said that two rockets hit part of the Kawergosk refinery northwest of the Kurdish capital Arbil, causing "minor material damage".

A fire broke out at the site but was "quickly contained", one of the sources said.

The rocket attack was not immediately claimed.

The Kurdish counter-terrorism forces said the rockets were fired from the town of Bartella in neighbouring Nineveh province.
