Iraqi and Iranian soldiers traded fire on Thursday on the northern border between the two countries, Iraqi media reported.

"The border guards of Iran and Iraq exchanged fire for about half an hour on the Iraqi border at the territory of the Kurdistan autonomous region," said Ahmed Gharib, head of Iraq's border guards in the province of Sulaimaniya, according to Iraq's Alsumaria news agency.

The officer said the incident occurred because the Iranian forces took the Iraqi border guards as an Iranian anti-government Kurdish group and started the shooting.

An Iraqi officer was captured by the Iranian forces and taken into the Iranian territory, the report said. "Negotiations with the Iranian side are underway and they promised to release the officer Friday morning," the chief was quoted as saying.

No casualties have been reported in the incident.
