More than 400 of the 2,000 expected Russian peacekeepers arrived in Armenia on Wednesday, Russia's Ministry of Defense says.

The peacekeepers will build observation points along the Nagorno-Karabakh line of contact as well as at the Lachin corridor connecting Armenia and Nagorno-Karabakh, it said in a statement Wednesday.

Meanwhile, crowds are protesting in the Armenian capital of Yerevan after its government conceded to Azerbaijan's cease fire terms. But citizens are celebrating in the Azerbaijan capital city of Baku.

Hundreds of people gathered on the streets of Baku, waving Azerbaijan, Turkey and even Israel flags. The opposite was true in the streets of Yerevan, where people protested the decision made by Armenian Prime Minister Nikol Pashinyan. Some protesters reportedly stormed Pashinyan's residence, calling him a traitor.  

A group of demonstrators reportedly broke into the parliament and beat one of its speakers, Ararat Mirzoyan. He was taken to the hospital and required surgery. Opposition leaders called for Pahshinyan's resignation, saying that Armenia could have negotiated a better deal. Pahshinyan defended his actions, saying that the public needs to understand that there was no other choice but to stop the fighting.

Following the signing of the peace agreement, Russia sent out peacekeeping forces to the ethnic Armenian-occupied territories in the Caucasus Mountains. Their arrival cemented Azerbaijan's triumph in the region following a six-weeklong conflict that resulted in the deaths of thousands of soldiers and civilians.

Azerbaijan has largely emerged victorious in its goals of retaking its territories in the Nagorno-Karabakh region, which is internationally recognized as belonging to the country. Since the war between the two nations had ended in the early 1990s, the area has been mostly occupied and controlled by Armenian groups.

Earlier this week Russian President Vladimir Putin announced that both sides had agreed to halt all hostilities. Azerbaijan will be getting back most of its territories while Armenian will be given control of some parts of the region, including the Nagorno-Karabakh capital.
