The head of the U.N. team, Pekka Haavisto, said the three places of concern were an ammunition storage site near Sarajevo, a nearby tank repair factory and a military barracks in Han Pijesak in eastern Bosnia.

The areas were hit by NATO air strikes using depleted uranium armor-piercing rounds in 1995 as part of an effort to curb attacks by Serbs in Bosnia-Herzegovina.

Investigators had probed 14 sites over the past month.

NATO authorities last year launched a probe into the possible link between the use of depleted uranium ammunition in the Balkans and increased cancer rates among peacekeepers who had served in the area. But a committee reported that medical research so far had not proved any link between the weapons and the health problems.
