The Secretary-General of the United Nations, Antonio Guterres, said that the external intervention "reached unprecedented levels" in Libya, with "the delivery of advanced equipment and a number of mercenaries involved in the battles."
Guterres expressed his concern about the build-up of military forces in the vicinity of the city of Sirte, located between Tripoli in the west of the country and Benghazi in the east.
For her part, the US delegate to the Security Council said, "The developments and military build-up in Sirte area are of concern to us."
"There is no place for mercenaries in Libyan territory ... and all Libyan sides must cease fire," she added.
As for the British Minister of State for Middle East and North Africa Affairs, he indicated in his speech that violations of the arms embargo on Libya continue.
While the French delegate to the Security Council stressed, "There is no military solution to the Libyan crisis."
Over the past few months, Turkey has brought thousands of Syrian mercenaries to Libya to fight in the ranks of the armed militias that control Tripoli.
Not only did Ankara send mercenaries to Tripoli, it sent officers from its army and set up operations' rooms inside the Libyan territory to support the Fayez al-Sarraj government which is protected by the militias.
