The Commissioner, Nils Muižnieks, strongly condemns forced returns of children, detention of children, the use of X-ray tests to determine age, and recent proposals by the Netherlands, Norway, Sweden and the United Kingdom to set up a 'return house' called the 'Welcoming Centre' in Afghanistan to facilitate the return of children. While aimed at family reunification, the idea has been opposed due to risks of sexual and military trafficking, the high difficulty of family tracing in Afghanistan, and the risks of child disappearance and persecution.
