Between October 2013 and October 2014, the Italian government ran Operation Mare Nostrum, a naval and air operation intended to reduce illegal immigration to Europe and the incidence of migratory ship wreckages off the coast of Lampedusa. The Italian government ceased the operation as it was judged to be unsustainable, involving a large proportion of the Italian navy. The operation was replaced by a more limited joint EU border protection operation, named Operation Triton managed by the EU border agency, Frontex. Some other European governments, including Britain's, argued that the operations such as Mare Nostrum and Triton serve to provide an "unintended pull factor" encouraging further migration.
