The Arab League, United Nations, European Union and the African Union on Tuesday demanded an immediate withdrawal of all foreign forces from Libya.
In a statement after a videoconference by its leaders, the so-called "Libya Quartet" demanded "full compliance with the arms embargo and the immediate and unconditional withdrawal of all foreign forces and mercenaries from the entirety of Libya's territory."
The much-violated arms embargo has been in place since 2011, when an uprising toppled longtime Libyan dictator Muammar Gaddafi during the regional upheaval known as the Arab Spring.
The UN estimates that some 20,000 foreign fighters, mainly troops from Turkey and its Syrian mercenaries.
In recent weeks, the possible departure of Syrian mercenaries has been raised.
During its meeting, the Libya Quartet "condemned the continued violations of the UN arms embargo and emphasized that all external military intervention in Libya is unacceptable."
It also called for "the sustained implementation of measures to fully identify and dismantle these groups."
