This picture taken on June 3, 2016 shows 13 year-old Viet (L) lying in recovery at a hospital with his brother after losing several fingers to an unexploded bomblet in Xieng Khoang. The legacy of the secret bombing campaign the United States conducted in a sideshow to the Vietnam War and its enduring consequences will feature prominently during a visit September 2016 by Barack Obama, the first ever by a US president to Laos. During the trip he is expected to announce the ramping up of a US programme to clear unexploded devices, echoing similar moves Washington took in Vietnam as relations between the two former foes blossomed. / AFP PHOTO / ALISON MCCAULEY / TO GO WITH AFP STORY LAOS-US-DIPLOMACY-CONFLICT-OBAMA,FOCUS BY CORALINE MOLINIEALISON MCCAULEY/AFP/Getty Images
