Paris - The EU Thursday called for cooperation between all "conflict parties" to investigate a shooting attack on unarmed peace observers near the city of Gori close to the breakaway republic of South Ossetia.

The EU presidency, currently held by France, strongly condemned the attack and said it expected cooperation from all sides.

Nobody was wounded in the attack on Wednesday, which was reported by Georgian media. The television channel Rustavi-2 showed images of an off-road vehicle belonging to the OSCE with several bullet holes in the side.

In the aftermath of the Russia-Georgia conflict last August, an international agreement was reached for the OSCE to post military observers in the region to watch over the ceasefire accord. Besides the OSCE, there are also more than 200 European Union observers.

Despite the ceasefire, however, explosions and firefights have repeatedly bee reported in the area in which more than 200 EU are based.

Officials in South Ossetia dismissed the reported shooting incident as a "provocation" carried out by the Georgian side. (dpa)
