No justification for Uighur concentration camps in China: US

Talking about China's treatment of Uighur Muslims, the US Deputy National Security Adviser Matt Pottinger said there's no justification for the country maintaining "concentration camps". According to the UN, over 1 million Muslims have been detained in Xinjiang. Last week, US National Security Adviser Robert O'Brien had said that China was perpetrating "something close to" a genocide.
