Italy said the operations of its navy and coast guard in the Mediterranean are obstructed by NGOs as the flow of migrants to the country grows, local media reported on Monday.
Deputy Prime Minister Matteo Salvini said these concerns should be taken seriously.
Rescue ship Louise Michel was detained over the weekend in the Mediterranean port city of Lampedusa by Greek authorities.
"It is Italy that is under attack, not the NGOs,” said Salvini, adding that “immigration to Italy cannot be regulated by private bodies funded by foreign countries.”
