The mayor of Rome, who is from the anti-establishment Five Star Movement, has asked Italy’s government not to send more migrants to the city.
Virginia Raggi said more arrivals could exacerbate social tension.
An estimated 40% of the migrants in Italy have a valid claim to asylum or leave to remain on humanitarian grounds, AFP news agency reported.
The others are deemed to be illegal economic migrants and face deportation, but this can be difficult to arrange in practice because their countries of origin sometimes refuse to take them back.
