ANSWER: Both
Explanation:
The Triton is under Italian control, began on 1 November 2014 and involves voluntary contributions from 15 other European nations (both EU member states and non-members). Current voluntary contributors to Operation Triton are Croatia, Iceland, Finland, Norway, Sweden, Germany, the Netherlands, France, Spain, Ireland, Portugal, Austria, Switzerland, Romania, Poland, Lithuania and Malta. The operation was undertaken after Italy ended Operation Mare Nostrum, which had become too costly for a single country to fund; it was costing the Italian government €9 million per month for an operation that lasted 12 months. The Italian government had requested additional funds from the other EU member states but they did not offer the requested support.
