ROME (Reuters) – The Italian government, looking to stem a flow of migrants into the country, has drawn up a draft code of conduct for non-governmental organizations operating in the Mediterranean Sea, an official said on Wednesday.

The 11-point plan is expected to be presented in the coming days to some nine NGOs who regularly deploy rescue boats to international waters just off the Libyan coast.

If any group refuses to accept the terms, they risk being barred access to Italian ports, meaning they would have to divert to other countries to disembark any migrants.

Among the proposed new rules will be a ban on making phone calls or firing flares that might signal to human traffickers that they could push their migrant boats out to sea.

The NGO vessels will also be obliged to let police travel with them to help root out any human traffickers hidden amongst the migrants. In addition, the boats will no longer be allowed to transfer refugees to other ships, but will instead have to bring them to port themselves, limiting their operations.

Amnesty International and Human Rights Watch, which received a leaked draft of the Italian document, warned that the proposals could have a disastrous impact on the NGO missions.

“Attempts to restrict NGO search and rescue operations risk endangering thousands of lives by limiting rescue boats from accessing the perilous waters near Libya,” said Iverna McGowan, a senior director with Amnesty International.

Some 85,217 migrants have come to Italy so far this year, according to data released by the interior ministry on Wednesday, up 8.9 percent on the same period in 2016.

Encouraging Sea Crossings?

In all, more than 600,000 newcomers, the majority from sub-Sahara Africa, have reached Italy over the past four years, with tens of thousands more expected in the coming months.

A small flotilla of charity boats have become increasingly important in rescue operations, picking up more than a third of all migrants brought ashore so far this year against less than one percent in 2014, according to the Italian coastguard.

Rome suspects their presence just outside Libyan territorial waters encourages migrants to risk their lives and put to sea. NGOs deny this and say thousands more would die if their boats were not present in the southern Mediterranean.

More than 13,000 people are estimated to have drowned since 2014 trying to make the dangerous crossing to Italy.

The code of conduct will include a categorical ban on NGOs entering Libyan waters unless human life is clearly in danger.

While viewing the NGOs with increasing suspicion, the Italian government has also grown frustrated with its EU allies, saying they are not doing enough to help it tackle the crisis, including by taking in many more of the new arrivals.

Looking to improve cooperation, Italian Prime Minister Paolo Gentiloni met French President Emmanuel Macron and German Chancellor Angela Merkel on Wednesday. However, there was no sign of any pledges to help relieve the pressure on Italy.

“Progress has been made regarding migration policy, but it is not yet sufficient,” Gentiloni told reporters.
