This means they struggle to access health care, education and public services. "UNHCR is calling on State authorities to take every possible measure to ensure people's safety and welfare.

"Those with a voice in the public domain have a responsibility to ensure their language does not further inflame the situation, and that foreigners do not become scapegoats for complex socio-economic challenges," said Yaxley.
