Cunningham posted a selfie on Twitter on Tuesday with the young Al-Heraki in Stuttgart after he stopped by to see the teen and his family.
My refugee friend Hussam that I met in Jordan. I've just surprised him in Stuttgart! pic.twitter.com/ItJc9yi9KE— liam cunningham (@liamcunningham1) October 11, 2016
Al-Heraki and his family decided to flee Syria and go to Jordan after his school was hit by missiles during his exams, according to Reuters.
He met Cunningham last month when the Irish actor was visiting his refugee camp in Jordan with aid organization World Vision.
“I wanted to personally welcome him to Europe,” Cunningham said on Wednesday.
After meeting in Jordan, the two stayed in touch through WhatsApp and Skype.
“He had actually written to say that we would see each other again soon, but when yesterday he suddenly was standing behind me, I was speechless,” the 16-year-old said.
