A teacher has opened fire at an education department office in Saudi Arabia 's southern Jazan province, killing six colleagues, officials have said.

Two other people have been wounded in the assault, which took place in the remote community of Ad Dair.

The attacker has been arrested, an official said.

No motive has been given for the attack, and authorities are treating it as a criminal act.

Mass shootings are rare in Saudi Arabia but it has faced recent attacks by the so-called Islamic State.

Jazan sits on the border with Yemen. Saudi Arabia has led an air campaign against Shia Houthi rebels in Yemen and violence in the border region has been frequent in recent months.

State TV posted a picture on Twitter that showed ambulances outside the building where the shooting happened.

Police have cordoned off the office compound, local media reported.
