UPDATE 2-Two Afghans, ISAF soldier killed in Koran protest

(Adds Lithuanian minister's remarks)

HERAT, Afghanistan, May 22 (Reuters) - A protest over the shooting of the Koran by a U.S. soldier in Iraq turned violent in Afghanistan on Thursday, killing a Lithuanian soldier and at least two Afghan civilians.

The NATO-led International Security Assistance Force (ISAF) said Afghan police killed the two civilians and wounded seven others after a rock-throwing crowd tried to storm a base in the town of Chaghcharan.

Police spokesman Abdul Mutalib said three civilians were killed in the incident.

The soldier was killed by gunfire, but it was not clear if the shots came from the crowd or from Taliban insurgents, an ISAF spokesman said. There were no indications that it was the result of so-called friendly fire.

The dead soldier was a Lithuanian from the Provincial Reconstruction Team (PRT) in Chaghcharan, the Lithuanian Defence Ministry said. One other soldier was wounded, ISAF said.

"Protesters set on fire a fuel station opposite the PRT base before trying to storm it," General Ikramuddin Yawar, chief of police in western Afghanistan, told reporters.

He said 12 protesters and 11 police were wounded by gunfire and soldiers from the PRT fired into the crowd after some of the protesters fired at police and the base.

The protest was organised by students from a religious school, and the situation was now under control, Yawar said.
