A six-year-old boy's letter written to President Barack Obama, offering a place in his family home to a Syrian refugee, was read out at the United Nations.
Alex, from New York, penned the letter after seeing a picture of Omran Daqneesh, a boy whose bloodied face highlighted the trauma children have faced in the Syrian conflict.
Mr Obama quoted words from Alex's letter while attending a UN summit on the refugee crisis this week.
Politicians at the summit applauded the letter after it was read out.
The White House then filmed Alex reading the letter himself from his home.
"We should all be more like Alex", President Obama told the summit.
"Imagine what the world would look like if we were. Imagine the suffering we could ease and the lives we could save".
President Obama announced that the US will welcome more refugees from around the world, increasing the number of people the country receives by 40% over the next two years - to 100,000 in 2017.
