Actor Jack O'Connell is supporting Blippar and UNHCR's new campaign, starring in a video to raise awareness about the refugee crisis, marking World Refugee Day.

The two organisations have teamed up to encourage people to sign the #WithRefugees petition by scanning their hands on the Blippar app, to show they are 'raising their hands' to support the campaign. Users will then be able to watch the video featuring O'Connell, titled Home. UNHCR has also released a new video for World Refugee Day (https://youtu.be/Jtv4LCXEGEU), starring Goodwill Ambassadors Cate Blanchett, Khaled Hosseini and Alek Wek, and celebrities including Will Ferrell, Scarlett Johansson, Ben Stiller and Kristin Davis.
