There's another cease-fire agreement in Syria, but this one is different.
Recently, there have been a few cease-fires in the war-torn country, but many have been centered around the city of Aleppo.
The two countries were also responsible for negotiating the recent cease-fire in Aleppo that let thousands evacuate.
According to Russian media, the truce includes the Syrian government and seven major opposition groups. Terror groups ISIS and Jabhat al-Nusra weren't part of the deal.
The United States helped negotiate 2016's two failed cease-fires but wasn't involved in this new one.
Russian President Vladimir Putin says the agreement is "fragile." However, if it holds, peace talks between the Syrian government and opposition groups are supposed to begin.
