France and Germany marked 50 years of reconciliation Sunday but the desecration of German war graves marred a meeting of their leaders that could ease tensions on tackling the euro debt crisis.

The gravestones of 40 German soldiers from World War I have been desecrated at a military cemetery in the Ardennes region of northern France, the interior ministry said Saturday.

The death toll from severe flash floods in Russia's southern Krasnodar region climbed to 150 people from the figure of 146 released earlier by investigators, a police spokeswoman said Sunday.
