As the refugee crisis continues across Europe, millions of displaced people are travelling huge distances to reach a place of peace.
Embarking on such a journey is 17-year-old Syrian refugee, Aslan, and making the trip with him against all odds is his dog, Rose.
According to the video, originally posted to Facebook by the UN High Commissioner for Refugees (UNHCR), Aslan fled Damascus, travelling over 300 miles on foot as part of his journey to the Greek island of Lesbos.
The UNHCR asked the teenager why he continues to carry Rose in her carrier, making it a more difficult journey for himself.
Aslan simply replied in a way that many can resonate with, stating: "I love my dog."
He was told repeatedly not to bring Rose, but in his persistence he refused to be separated from the dog. Even making Rose her own handmade passport.
According to a June UNHCR report, almost 60 million people worldwide were displaced from their homes by conflict at the end of last year. Of those, almost 20 million were considered refugees, an increase of more than 3 million people from 2013.
Since early 2011, the main reason for the acceleration has been the war in Syria, now the world's single-largest driver of displacement. Every day last year on average 42,500 people became refugees, asylum seekers, or internally displaced, a four-fold increase in just four years.
UN High Commissioner for Refugees António Guterres said: "We are witnessing a paradigm change, an unchecked slide into an era in which the scale of global forced displacement as well as the response required is now clearly dwarfing anything seen before."
