The Grace Kelly star was born in Beirut but moved to Paris, France with his family when he was still a baby, and he returned to his homeland over the weekend (19-20Dec15) for a mission with UNHCR, The United Nations' Refugee Agency.

Mika met with Syrian refugees who fled the conflict in the country and are now living in a derelict chicken farm across the border in Lebanon, documenting his journey in a series of posts on social media and in a film for the BBC.

He started his social media posts by declaring, "So good to be back in Beirut!" before later sharing a video which showed him making music with a group of refugees.

In another clip which he shared via Twitter.com, he declared, "In an informal settlement here in the banana plantation in Lebanon, it's moving, but what I'm taking away more than anything, is the strength of human resilience."
