According to Secretary of State Antony Blinken, it would be a "good thing" if Russia could utilize its clout in the area to put an end to hostilities between Armenia and Azerbaijan.

"If Russia can actually use its own influence for good, which is to again calm the waters, end the violence and urge people [of Armenia and Azerbaijan] to engage in good faith on building piece, that would be a positive thing," Blinken stated during a press conference.

Last night, Armenia accused Azerbaijan of striking its territory with artillery and drones. This comes right after a ceasefire was reached between Armenia and Azerbaijan.

Both Russia and Iran issued calls earlier today for resolving the Armenia-Azerbaijan conflict. "We are in close contact with Baku and Yerevan.

In the same context, Iran has expressed its readiness to help settle the conflict between Armenia and Azerbaijan and is calling for restraint and resolution of disagreements through peaceful means and based on international law, the Iranian Foreign Ministry said.
