Only 5,000 resettlement places across Europe are to be offered to refugees under the emergency summit crisis package to be agreed by EU leaders in Brussels on Thursday, The Guardian newspaper reported.

A confidential draft summit statement seen by the Guardian indicates that the vast majority of those who survive the journey and make it to Italy – 150,000 did so last year – will be sent back as irregular migrants under a new rapid-return program coordinated by the EU’s border agency, Frontex.

The draft summit conclusions also reveal that hopes of a major expansion of search-and-rescue operations across the Mediterranean in response to the humanitarian crisis are likely to be dashed, despite widespread and growing pressure.

The summit statement merely confirms the decision by EU foreign and interior ministers on Monday to double funding in 2015 and 2016 and “reinforce the assets” of the existing Operation Triton and Operation Poseidon border-surveillance operations, which only patrol within 30 miles of the Italian coast.

The European council’s conclusions said this move “should increase the search-and-rescue possibilities within the mandate of Frontex”. The head of Frontex said on Wednesday that Triton should not be an operation primarily aimed at search and rescue.

Instead, the EU leaders are likely to agree that immediate preparations should begin to “undertake systematic efforts to identify, capture and destroy vessels before they are used by traffickers”. The joint EU military operation is to be undertaken within international law.

The statement describes the crisis as a tragedy and says the EU will mobilise all efforts at its disposal to prevent further loss of life at sea and to tackle the root causes of the human emergency, including co-operating with the countries of origin and transit.
