Fears Nagorno-Karabakh conflict a threat to regional stability

According to Armenia, Ankara is also giving military support. Animosity between Turkey and Armenia has been festering since the killing of 1.5 million Armenians in World War I, which more than 30 countries have since described as a genocide.
