A 14-year-old boy from Afghanistan told British TV broadcaster Sky News about the nights he cried and missed his family while living in a makeshift refugee camp in northern France.
Aemal Khan is part of a group of 14 young migrants who arrived in London this week from the Calais encampment, to be reunited with relatives in Britain.
Aemal was reunited with his older brother, Asif Khan. The two had not seen each other in over a decade.
"It was a great moment when I saw him after a long time, more than 10 years, around 11 years. It was great to meet him and hug him and kiss him.
"He was so small when I saw him in the first (when I last saw him)," Asif Khan told Sky News.
Aemal and Asif's reunion comes as a British lawmaker suggested that young migrants should have their teeth tested to ensure they are really children.
Conservative legislator David Davies said migrants who arrived this week "don't look like 'children" and that British people "want to help children but we don't want to be taken for a free ride."
British dentists have rejected Davies' suggestion saying that the method was inaccurate for assessing age, adding that "it is both inappropriate and unethical to take radiographs of people when there is no health benefit for them."
France says it will close the Calais camp by the end of the year.
That means 6,000 to 10,000 migrants will need to be relocated, including up to 1,300 minors, according to different estimates from charities operating in the camp.
