Armenia-Azerbaijan border fighting escalates; 16 killed

Armenia and Azerbaijan forces fought on Tuesday with heavy artillery and drones, leaving at least 16 people killed on both sides, including an Azerbaijani general, in the worst outbreak of hostilities in years. Skirmishes on the volatile border between the two South Caucasus nations began Sunday. The two neighbors in the South Caucasus have been locked in conflict over Nagorno-Karabakh, a region of Azerbaijan that has been under the control of ethnic Armenian forces backed by Armenia since a war there ended in 1994. International efforts to settle the conflict have stalled.
