Italy won’t allow two ships allegedly carrying migrants and asylum seekers from Libya to reach its shores, Interior Minister Matteo Salvini said, in comments highlighting the risk for further spats between the populist government in Rome and its European Union peers.

“Two other ships with the flag of Netherlands -- Lifeline and Seefuchs -- have arrived off the coast of Libya, waiting for their load of human beings abandoned by the smugglers,” Salvini wrote Saturday on his Facebook account. “These gentlemen know that Italy no longer wants to be complicit in the business of illegal immigration, and therefore will have to look for other ports (not Italian) where to go.”

Salvini’s battle to curb arrivals from across the Mediterranean has rocked relations between the new Italian governing coalition and France just over a week after the administration led by the League party and the Five Star Movement was sworn in. The spat could threaten broader efforts led by France and Germany to reform euro area governance.

Almost 60 percent of Italians are in favor of closing the country’s ports, supporting Salvini’s anti-immigration strategy, Ferdinando Pagnoncelli, president of polling company Ipsos Italia, wrote Saturday in Corriere della Sera, citing a survey conducted on June 12-13.

Lingering political tensions over the unresolved question of how to control immigration from outside Europe have now broken out into the open, and the fallout is reshaping alliances and stoking old rivalries from Rome to Berlin, Paris and Vienna.

“Italy is facing giant challenges and I can understand that in the past Italy got the feeling it didn’t receive enough solidarity from European countries,” German Foreign Minister Heiko Maas said in an interview with Corriere della Sera, adding that he invited his Italian counterpart Enzo Moavero Milanesi to Berlin.

Salvini, leader of the anti-immigrant League, lost no time in falling out with some close European allies over his decision to deny access to port for a refugee vessel earlier this month. His stance also forced uncomfortable decisions in Spain which was forced to take in a ship turned away from Italy and is threatening Chancellor Angela Merkel, who faces renewed domestic turbulence over her open-door stance on migrants that could yet spell her early departure.

“As a minister and a father, they can attack me and threaten me as much as they want, but I do not give up and I do it for the good of all.” Salvini added on Facebook
