Nagorno-Karabakh conflict: BBC visits Azerbaijan's frontline
Reports suggest that fighting is continuing near the disputed region of Nagorno-Karabakh.
The territory, which sits within the legally-recognised borders of Azerbaijan, is controlled by forces backed by neighbouring Armenia.
Armenia says it is not directly involved in a conflict, but that is rejected by Azerbaijan.
The past month has seen the worst violence there since the mid-1990s. The BBC’s Tom Burridge travelled to the region of Agdam in western Azerbaijan.
