NAGORNO-KARABAKH – In the most serious fighting since 1994, at least 30 soldiers were killed after Azerbaijan and Armenia fought over the disputed Nagorno-Karabakh region. Azerbaijan says it has responded to international calls from world powers including Russia and Germany to end the fighting with separatist rebels. Turkey has backed Azerbaijan’s calls for a ceasefire. Armenia says fighting is still happening. Nagorno-Karabakh is part of Azerbaijan – but the mainly ethnically Armenian population want to part of Armenia. Both neighbours fought a war over the south Caucasus region in 1994 and there have been sporadic outbursts of violence since.
