Yerevan has accused Turkey of sending mercenaries to Nagorno-Karabakh, who had fought for Azerbaijan there. Such complaint was submitted to the European Court of Human Rights (ECtHR). The European Parliament has also condemned sending mercenaries by Ankara.

The "Caucasian Knot" has reported that on May 19, the European Parliament called on Turkey to recognize the Armenian Genocide in the Ottoman Empire for further reconciliation of the two nations.

"Turkey decided to support Azerbaijan and facilitate the escalation in Nagorno-Karabakh instead of supporting the calls of the OSCE co-chairs to end the hostilities," says the report, quoted by the Armenian Embassy in Belgium.

In October 2020, France and the United States released data on the transfer of militants from Syria via Turkey to the Karabakh conflict zone. Armenia accused Turkey of involvement in shelling of Karabakh dwelling settlements.

Arman Tatoyan, the Armenian Ombudsperson, said on the Facebook that the above complaint noted that during the autumn war of 2020, Turkey provided military support to Azerbaijan and thereby violated the rights of the population of Karabakh and Armenia to life, protection from inhuman treatment, property rights and a number of other fundamental rights.
