Italy blames EU for migrant boat crisis

Italy's hardline interior minister Matteo Salvini said he would hold the Netherlands and the European Union "responsible" for the fate of 42 migrants that Rome has blocked from disembarking at Italian ports for over a week.

The Dutch-flagged rescue boat Sea-Watch 3 has been stuck in the Mediterranean since rescuing 53 migrants drifting in an inflatable raft off the coast of Libya on June 12.

While eleven of those on board the Sea-Watch were allowed to disembark -- including two pregnant women -- the vessel was denied permission to dock in Italy and has refused to return those rescued back to crisis-hit Libya, saying Tripoli was not a safe port.

Salvini, who is also deputy prime minister and leads the powerful right-wing League party in the ruling coalition, has seen his popularity soar in the last year with a hard line against migrants which has included closing ports to rescue vessels.

He said on Sunday that he had written to his counterpart in the Netherlands.

"I am incredulous because they are not interested in a boat that is flying their flag... and has been floating in the open sea for 11 days," he said in a statement.

"We will hold the government of the Netherlands and the European Union, distant and absent as usual, responsible for all that happens to the women and men on board the Sea-Watch," he added.

Ten of the Sea-Watch migrants were allowed to disembark a week ago on the Mediterranean island of Lampedusa, which lies between the Italian mainland and the north African coast, while a sick man was also able to leave the boat on Saturday.

But 42 people remain on board the ship, which is operated by a German aid group.

Malta on Sunday said its navy had rescued a group of 37 migrants in difficulty in the Mediterranean. They are expected to arrive on the island during the day.

Rome and Valletta insist on there being a fair distribution of migrants to other EU countries, while countries such as France say migrants should disembark at the closest port and then be voluntarily redistributed around Europe.

More than 12,000 people have died since 2014 trying to flee Libya to Europe by what the UN refugee agency calls the "world's deadliest sea crossing".
