[...] The attack in Armenia's south-eastern Syunik province also comes days after Azerbaijan's President Ilham Aliyev won a fifth term in office, and local commentators have raised concerns that he may be considering further military action to seize Armenian territory.

The South Caucasus territory, between the Black Sea and the Caspian Sea, had been recognised internationally as part of Azerbaijan but had been in Armenian hands for more than 30 years.
