The previous night the mood outside the barracks had been less welcoming. About 200 people belonging to a right-wing party and an extremist movement protested, carrying banners that read “Italians first.” Migrants peeked uneasily from the barracks’ windows overlooking the piazza, before closing the shade.

It was the third such protest in recent days, with anti-migrant campaigners pledging more. Tensions over migrants have been rising in Italy amid persistent arrivals creating a crunch in the housing system in the months since Rome has stepped up its border controls under pressure from European neighbors.

Organisers of Tuesday’s welcome event said that politicians on the right have been using the crisis in arrivals to stir up anti-migrant sentiment, leveraging Italy’s economic stagnation to create uncertainty and fear. They decided on the welcome party after the city’s plans to open the barracks to migrants became a political flashpoint, hoping that familiarity with the newcomers would help ease residents’ reservations.

“It is very important that we meet each other and try to face the future in a different way. This is one reason for this event. The other is that politicians are trying to use the migrant issue to get votes,” said Selana Tesfai, a founder of the Zone 8 Solitary Committee.

Migrant arrivals in Italy have topped 153,000 in the first 10 months of the year, close to that of all of last year although still shy of the record 170,000 in 2014. But with fewer heading north, Italy has had to come up with more migrant housing and aid - and more often has met local resistance.

Last week, dozens of residents of the small Adriatic clamming town of Goro blocked a road to prevent a dozen female migrants from being housed in the local hostel. The act was widely condemned, but received support from right-wing politicians.

Milan remains the city with the most migrant arrivals in Italy, largely because it is seen as a transit point, the city official charged with social policy, Pierfrancesco Majorino, told The Associated Press at the welcome party.

“In these months we have seen many small manifestations against (migrants) in northern Italy, even in Milan,” Majorino said. “This is the first time there is a mobilisation to welcome them. I find this very nice.”

Organisers said they have approached the charity that is running the barracks shelter to create programmes so the migrants feel at home, such as sporting events, cooking classes and a map of places in the neighbourhood that want to help with the transition.

Since the crisis began on October 18, 2013, 108,000 migrants have passed through Milan. From 2013-2015, just 2 per cent of migrants requested asylum; that has now jumped to 75 per cent, Majorino said. Currently, the city is housing 3,760 migrants.
