Fighting between Armenia and Azerbaijan continued for the ninth consecutive day today, with hundreds of people (including soldiers and civilians) being killed since last Sunday. The violence is the latest development in a decades-long dispute between the two nations (relating to the Nagorno-Karabakh region), and marks the deadliest escalation since the 1990s.
More context: The conflict began in the late 1980s, when the ethnic Armenians who control the Nagorno-Karabakh region (which lies within Azerbaijan’s border) voted to become part of Armenia. That decision ultimately led to a war between the two nations that temporarily ended with a ceasefire in 1994.
