Gun battle kills several in Nagorno-Karabakh

Azerbaijan and Armenia have accused each other of triggering an exchange of gunfire in the disputed Nagorno-Karabakh. The clash allegedly killed up to 16 people – the biggest death toll in fighting there for several years.

There have been conflicting reports of casualties from both sides.

A fragile truce had been reached in the mid 1990s following a bloody war that killed up to 35,000 people.

Moscow and Washington have expressed concern about the latest shootout and have called for restraint.
