Azerbaijan's president threatens war with Armenia via Twitter

Azerbaijan’s president has threatened war with Armenia via Twitter, after dozens were killed in clashes over a disputed area of land that both countries lay claim to.

In a lengthy series of tweets,President Ilham Aliyev said several Azeri lives had been lost in clashes over Nagorno-Karabakh, and pledged to restore what he said was his country’s “territorial integrity”.

The two sides began fighting over the mountainous region in the final years of the USSR. Armenian forces took de facto control of Nagorno-Karabakh, where some 90%  of the population is ethnic Armenian, but it remains part of Azerbaijan under law.

A Russia-brokered ceasefire was signed in 1994 after six years of fierce fighting
