“I am concerned about the resumption of hostilities along the line of contact in the conflict zone in Nagorno-Karabakh and call for an immediate cessation of hostilities,” she said in a statement.
The diplomat called on all parties to respect humanitarian law, in particular to ensure the protection of civilians.
Earlier, German Chancellor Angela Merkel, in telephone conversations with Armenian Prime Minister Nikol Pashinyan and Azerbaijani President Ilham Aliyev, called for a truce.
The Kremlin declared the need for an early ceasefire and noted that any statements about military support for one of the parties to the conflict provoke an aggravation.
On the morning of September 27, it became known about the resumption of armed clashes between Armenia and Azerbaijan in the Nagorno-Karabakh region.
Both sides accuse each other of escalating the conflict.
