"Spain is not the safest port for this ship, as it is not the closest," the source said adding that "it's not about reluctance to accept the ship," as final decision is yet to be made.
Last week, humanitarian non-governmental organizations (NGO) SOS Mediterranee and Doctors Without Borders that operate the Aquarius called on European governments to provide a safe port of disembarkation after the vessel rescued 141 undocumented migrants from the Mediterranean. Currently the ship is in the international waters near Malta and Italy.
In June, Italy and Malta categorically denied entry to Aquarius that had over 600 migrants on board at the time. The Spanish authorities said they were ready to allow the vessel to dock at its eastern port. Some of the migrants were relocated to Italian ships the Orione and the Dattilo, and the three ships eventually arrived in Valencia.
According to the International Organization for Migration (IOM), over 60,000 migrants have arrived in Europe by sea in 2018, while 1,524 were dead or missing.
