A teenageÌýÌýrefugee was found hanging in one of , according to reports on Thursday.

Mohamed Mahmoud Abdel Aziz, 19,Ìýis believed to have taken his own life at theÌýÌýsouth of the capital Tripoli on 5 June, according toÌýAl Jazeera.

Abdel Aziz’s body was left hanging for hours on end in the room that he shared with hundreds of people, asylum seekers told the pan-Arab news outlet.

After some detained asylum seekers at the centre took photosÌýofÌýthe teenager's body, Libyan authorities confiscated their phones to prevent the image from spreading online, other asylum seekers said.

Abdel AzizÌýcame from western Sudan’s region, which has witnessed years of war that has killed tens of thousands of people.

He was detained in an overnight raid for peacefully protestingÌýoutside the UN refugee agency's Libya office to call forÌýrelocation and evacuation, before being released in May.

He was arrested again days later andÌýtaken back to the facility.

It is believed that he took his own life at the centre shortly after.

Migrants in Libya, most of whom attempt to cross the Mediterranean Sea to Europe, languish in detention centres, some of them run by militias, for months or even years at a time.

"Mohamed got tired of this until he reached this level and he [killed himself]," an asylum seeker said of Abdel Aziz's plight.

Aid groups such as Doctors Without Borders (MSF) say migrant centres in Libya are overcrowded and unsanitary, and lackÌýfood, water and medical care.

There have been many violent deaths in the centres.

Ìýincluding torture, rape and slaveryÌýis rife in detention camps across the North African country.

The UNHCR has said that approximately 2,772 people were being held in detention centres across Libya as of 22 May.
