Police opened an investigation after suspected far-right militants hung nooses from lamp-posts during a visit by Kyenge to the Adriatic port of Pescara for a conference on immigration and citizenship. The nooses appeared along with posters signed by the neo-Fascist Forza Nuova party, one of which read: "Everyone should live in their own country."
Kyenge, who came to Italy 30 years ago and has Italian citizenship, has faced a shocking level of racist vitriol since being appointed to the Cabinet in April.
In an interview with Corriere della Sera, she said she received daily threats by email, letter and telephone. "The most terrible are the ones online - there are even death threats. We don't yet have a law on inciting racism, but we need one. I have to remain alert all the time."
Asked why she thought she had been targeted by such vile racism, she said she felt that some Italians were threatened by the "diversity" that had been brought to the country by immigration. "Some people struggle to accept that the country has changed," she said, adding that she did not think Italy was racist overall.
