Armenian and Azeri soldiers clash near contested Nagorno-Karabakh region

Rivals have accused each other of initiating fire which killed seven people

South Caucasus rivals Armenia and Azerbaijan have accused each other of initiating a fatal clash around the contested Nagorno-Karabakh region which killed seven soldiers.

The two neighbours - both formerly part of the Soviet Union - have fought repeatedly over the last 35 years for control of Nagorno-Karabakh, which is internationally recognised as part of Azerbaijan but home to a mainly ethnic Armenian population.
