The United Nations secretary-general says the U.N. mission in Libya should be cut substantially because of the new and more dangerous situation there.

Ban Ki-moon's report circulated Tuesday says the mission should be limited to 15 to 20 people inside the north African country while keeping a temporary base in Tunisia.

He stresses this "does not mean that the United Nations is disengaging from Libya."

Libya's neighbors are calling for more U.N. action amid chaos that includes two separate governments, multiple armed groups and the growing presence of the Islamic State group.

The mission evacuated from Libya last year and has been trying to find compromise between a Western-backed government and another backed by Islamist militias.

Ban says the mission's first goal must be ending the conflict.
