Azeri armed forces opened fire on an Armenian military unit in the border town of Vardenis, and miles away from a breakaway Nagorno-Karabakh region which has been the focus of clashes in the past few days, the Armenian defense ministry said. A civilian bus was set on fire after being hit by an Azeri unmanned drone, it said in a statement. Separately, Armenia denied an earlier report by Azerbaijan's defense ministry that the Armenian army had shelled the Dashkesan region on the border between the two countries.
