The ambassadors of major European countries to Libya expressed in a joint statement on Sunday deep concern about the human rights violations in Libya, voicing concern toward reported abuses of human rights and violations of international humanitarian law which they said continue to happen across Libya.

"The violations are against civilians and internally-displaced persons," the ambassadors said in a joint statement issued by the EU Delegation to Libya and included the voices of over a dozen of western countries, including the United States, Britain, Germany and France.

The statement also demanded those suspected of committing, ordering, or failing to prevent such acts of violations on all sides to be fully investigated.

The ambassadors also hailed the UN Security Council condemnation of human trafficking in Libya and the claims of slave trade in the country and elsewhere.

"We know that Libyan authorities had started already to investigate the reports, thus we urge them to come out with the results to the public." The statement reads.

They also called on Libyan parties to "work quickly and cooperatively to amend and fully implement the Libyan Political Agreement," citing the fact that it is the "only viable framework" throughout Libya's transitional period.

Ambassadors of Austria, Belgium, Bulgaria, Finland, Italy, Netherlands, Romania, Spain, and the EU Delegation to Libya also signed the joint statement that was released to mark the International Human Rights Day, and the 70th anniversary of the UN General Assembly's adoption of the Universal Declaration of Human Rights.
