UN experts expressed "grave" concern on Wednesday over the Italian government’s policy on migration and urged to reverse it, the Office of the UN High Commissioner for Human Rights (OHCHR) said.

"Italy’s proposed tightening of immigration rules will have a serious impact on migrants’ lives, and are of grave concern, UN human rights experts said today, urging the Government to reverse course … The government must adhere to the values enshrined in the Italian constitution, and the international commitments it signed up to," the statement read.

The UN experts underlined that the new government’s policy on immigration "fuels" a climate of hatred in Italy in regards to migrants and other ethnic minorities as well as those supporting these groups.

"Perpetrators of hate crimes must be held accountable and justice provided to the victims. Italian authorities should implement the national and relevant European legal framework and provide the needed responses to hate crime and the use of hate speech," the experts added.
