"In the interest of protecting safety of life at sea, ICS is therefore calling on all EU Member States to urgently address the legitimate concerns raised by the Italian government about the large number of rescued persons arriving in Italy, in order that the policy of prompt and predictable disembarkation - consistent with UNHCR principles - can be fully maintained, not just in Italy but in other EU Member States too".
The 629 migrants, including pregnant women and children, were saved by SOS Mediterranée on Saturday, but the Aquarius was caught in a dramatic standoff over the weekend in which Italy and Malta refused to allow it to dock.
"The people are frightened, they're very fragile, vulnerable and traumatized by their journey at sea, which would last another 48 hours", tweeted MSF coordinator Aloys Vimard, who is on board the boat.

It's not yet clear what Salvini and the new government have in mind, but it's worth remembering that the League's Roberto Maroni was interior minister in 2009 when Italy implemented its nefarious policy of literally pushing boats back to Libya.
"You can't create a precedent that will enable one European country to offload onto other European countries", he said.
Italy had argued that Malta, a tiny island nation that also is an European Union member, was the safest, closest port to the ship.
Italy's premier, Giuseppe Conte, a political novice who backs the 5-Star Movement, on Monday was touring towns in struck by a 2016 quake. If we continue to stand firm, then we will be able to stop the flow of migrants to Europe.
A handout photo made available by SOS Mediterranee shows the sea rescue of a total of 629 migrants.
"In the Italian case, turning this into a political weapon is despicable.it is clear that Europe must act more wisely, but we can not let these people die at sea", he said. This would mean already exhausted people rescued have to endure four more days travel at sea.
