DAKAR (Reuters) -The United Nations is "extremely concerned" that Mali has prevented its investigators from visiting a town where local troops and suspected Russian fighters allegedly killed hundreds of civilians, the world body said on Wednesday.

At least 300 men are believed to have been summarily executed during a March 27-31 raid on Moura, a town of about 10,000 inhabitants infiltrated by Islamist militants, according to a Human Rights Watch report.
