The Russian Foreign Ministry does not deny the risk of mercenaries from Syria and Libya, who are taking part in the ongoing fighting in Nagorno-Karabakh, penetrating into the country, said Russian Deputy Foreign Minister Oleg Syromolotov.

"Undoubtedly, such a risk cannot be denied," he said.

According to Syromolotov, there are no small details in the fight against terrorism, and it is important to work forward. "Russian law enforcement agencies are monitoring the situation very closely and, as they say, 'they are keeping their hands on the pulse,'" the Russian deputy FM concluded.
