The UN has painted a disturbing picture of the situation in Libya.
Five months after the fall of Tripoli, the Libyan capital, the security situation is getting worse, not better.
Militias operating outside the control of the interim government - the National Transitional Council (NTC) - remain heavily armed and they continue to detain, and sometimes even torture, hundreds of prisoners suspected of being loyal to Muammar Gaddafi, the former Libyan leader.
Revolutionary forces were involved in recent fatal clashes in Tripoli, Bani Walid and Gharyan - in the west, and Benghazi in the east.
Doctors Without Borders (MSF), the international medical humanitarian organisation, has decided to suspend its operations in detention centres in Misrata after confirming that detainees are being tortured and denied urgent medical care.
The UN says Libyan militias are holding thousands of people in secret detention centres, while the interim government struggles to assert its authority.
Navi Pillay, the UN Human Rights chief, in a report to the UN Security Council said she is deeply concerned.
“We know that at least 60 detention centres exist, of which only six are under the control of the authorities. We visited a number of them and have seen torture and other abuses in all of them ... it is widespread. Many of the detainees we had spoken to did not know why they were being held.”

Pillay said Libya’s revolutionary forces were holding more than 8,000 prisoners in about 60 secret detention centres, most of them accused of being loyal to Gadaffi.
