Watch 'Sesame Street's' Grover Cheer on the Refugee Olympic Team

With one day to go until the Olympic Games officially begin in Rio de Janeiro, one team can count on the support of a famous furry blue creature: Sesame Street's Grover.

On Thursday, Sesame Street tweeted a video of Grover cheering on the Refugee Olympic Team, a group of displaced athletes from Syria, South Sudan, Ethiopia and the Democratic Republic of Congo who will compete in the Olympic Games for the first time. The team was created in response to the worst displacement crisis in recorded history: More than 65 million people around the world are refugees, asylum seekers or internally displaced within their own countries due to violence, conflict and persecution.

A major driver of the crisis has been the Syrian civil war, which has resulted in nearly 5 million people fleeing the country since war broke out in 2011.

The 10-strong team will compete under the Olympic flag and march behind the host team, Brazil, during the opening ceremony on Friday. They will be staying at the Olympic Village with the other 11,400 athletes from more than 200 countries who are competing.

In a short video, Grover explains what a refugee is and why the displaced athletes are competing in the Olympics.

"They're called refugees because they had to leave their homes. Life in their countries was not safe for them. Leaving their homes was sad," Grover explains in the video. "But this summer, the athletes are getting a chance to do something they love: They are competing in the Summer Olympics as the Refugee Olympic Team!"

Sesame Street recently partnered with the International Rescue Committee, a U.S.-based refugee resettlement agency, to help educate refugee children in host countries. In May, the organization said it's working on developing educational materials for displaced children and their families who have escaped war and persecution.

Two Syrian swimmers are competing in Rio this month, including the refugee team's Yusra Mardini, 18, who helped save 20 refugees from drowning in the Mediterranean last year after they took a boat from Turkey to Greece. The team also includes five runners from South Sudan, a marathon runner from Ethiopia and two judokas from the Democratic Republic of Congo.

"By rallying behind the refugee athletes competing in the Olympics, we are telling refugees around the world that they are welcome and they are not alone," Margaret Huang, Amnesty International USA's interim executive director, said in a statement earlier this week.

"During the Olympic Games, we're sending the message that any human being who has been forced to flee the country they call home has the right to be safe and rebuild their lives, and that millions of people stand in solidarity with refugees," Huang said.
