Putin calls for end to Nagorno-Karabakh clashes

Russian President Vladimir Putin has called for an end to fighting after clashes broke out in the disputed Caucasus region of Nagorno-Karabakh.
TV pictures showed a burned out vehicle and craters after a night of gunfire and heavy shelling.
Azerbaijan and Armenia accused each other of starting the fighting, with both sides reporting casualties.
Nagorno-Karabakh has been in the hands of ethnic Armenian separatists since a war that ended in 1994.
