Treviso, August 12 - Police are investigating two new threats against Italy's first black cabinet minister, Cecile Kyenge. Kyenge, minister of Integration, has come under intense pressure and a relentless wave of racist attacks as well as abuse over her stand on immigration. One of the latest was a post by a former political activist on social network site Facebook about Kyenge suggesting, ''someone kill her''. The post, by Vittorio Milani of the separatist group Veneto Stato, called her stance on immigration and integration ''absurd'' and called for her execution. Antonella Tocchetto, a local city councillor and member of the Democratic Party, to which Kyenge also belongs, saw the post and called authorities. Tocchetto said that she had also been targeted for abuse and threats by Milani for supporting the right of Muslims to worship freely. Meanwhile, officials in Vicenza are upset by a message scrawled in large handwriting on a garage door that read: ''Kyenge-orangutan'' accompanied by symbols that looked like swastikas. The city's mayor called it a ''cowardly act that offends our city'' and police are investigating. The message may have been a reference to a senator from the anti-immigrant Northern League who compared Kyenge to an orangutan.
