The UN Secretary-General Antonio Guterres says there are three main challenges preventing progress in the Libyan file.

"It is vital to maintain peace between eastern and western Libya, stop violence, and expedite the holding of elections which results should be acceptable to all," Guterres told reporters at the UN HQ in New York on Wednesday.

He stressed the need to maintain peace in Libya, between the east and west, as well as within the capital, Tripoli.

The UN head underscored that the cessation of hostilities in Libya is essential for reaching an agreement between the House of Representatives and the High Council of the State on the legal amendments to hold the elections. "This is a very important issue because it is related to legitimacy," Guterres said.

He also urged all external parties involved in the Libyan conflict to support the peace process until legitimate elections that everyone accepts take place.
