EU Special Representative for the South Caucasus and the crisis in Georgia Toivo Klaar has weighed in on the situation on the Armenian-Azerbaijani border, after Azeri troops opened fire on Armenian army positions and near civilian settlements in the night of July 19-20.

"Deeply worrying developments continue on Armenia-Azerbaijan state border," Klaar wrote on Twitter.

"Reiterate our call for restraint and separation of forces & constructive engagement on border issues before new casualties are registered. European Union stands ready to assist the sides."

The head of Armenia's Yeraskh community, Radik Oghikyan, was injured in Azerbaijan's shooting from across the border late on July 19, the Ministry of Defense said earlier. The Ministry added that the Azerbaijani military used various caliber weapons, including grenade launchers, to shell the Armenian positions on July 19-20.

Head of Geghamasar community Hakob Avetisyan confirmed later that the Azerbaijani military also opened fire in the vicinity of the border settlements of Armenia's Gegharkunik province throughout the night of July 19-20.
