The territorial dispute between Armenia and Azerbaijan has erupted again with the heaviest clashes in years. At least 23 people were reported to have been killed on Sunday as the two ex-Soviet republics battled over the Nagorno-Karabakh region. The region is internationally recognized as part of Azerbaijan but controlled by ethnic Armenians. When it broke away in the early 1990s, tens of thousands died in fighting.
Armenia claims neighbours Azerbaijan, attacked civilian settlements in the disputed Nagorno-Karabakh region causing its residents to seek refuge in shelters.
Arch-foes Azerbaijan and Armenia have been locked in a territorial dispute over the mainly ethnic-Armenian region for decades.
