Libya's Defense Ministry's Military Prosecutor's Office issued an arrest warrant for Tobruk parliament-appointed Prime Minister Fathi Bashagha, following deadly clashes in Tripoli, the worst in the capital since a landmark 2020 ceasefire, which sparked fears of a major new conflict.

The prosecutor's office issued a written request for the arrest of Bashagha addressed to the police, intelligence services, as well as all security services in the country.

The warrant also ordered the arrest of Bashagha's key ally, Maj. Gen. Osama Al-Juwaili, the former head of the Tripoli-based military intelligence service; Bashagha's Minister of Health and government spokesperson, Othman Abdel-Jalil; and Mohammad Sowan, Libya's Democratic Party chairman.

In response, Bashagha blamed the clashes in Tripoli on Libyan Prime Minister Abdul Hamid Dbeibah and government officials.

"Under the orders of their leader, Dbeibah, caused security chaos in Tripoli, and they are held responsible for the repercussions due to their obsession with money and power," he added.

Bashagha accused Dbeibah of "exploiting state resources to form and back armed groups that consolidate his power by force."

Libya's rival premiers on Sunday have also exchanged accusations over the deadly clashes in Tripoli.

The Libyan Health Ministry said 32 people were killed and 159 were wounded during the fighting between rival armed groups which began overnight Friday and continued into Saturday, setting buildings on fire and damaging several hospitals.

The fighting came after months of mounting tensions between backers of Abdulhamid Dbeibah and Fathi Bashagha, whose administrations are fighting for control of the oil-rich North African country.

Dbeibah, whose government was installed in Tripoli in the country's west as part of a United Nations-led peace process last year, accused his rivals of responding to "foreign agendas".

Local media and experts said Bashagha had failed in what was his second attempt to dislodge his rival from the capital in three months. 

In a video address late Sunday, Dbeibah lashed out at "criminals" and "putschists" who "waged war on the capital with tanks and heavy weapons."

He vowed to "go after all those involved" and to relocate the headquarters of some armed groups outside the city center.

Earlier, Bashagha, who was appointed by Libya's eastern-based parliament this year, held Dbeibah and "his ruling family and his armed gangs" responsible for "the blood that flowed" in Tripoli, accusing them of wanting to cling onto power "at any cost."

Bashagha, a former Interior Minister, is backed by powerful eastern military chief Khalifa Haftar, whose 2019 attempt to seize the capital by force turned into a year-long conflict.

Dbeibah has refused to cede power on the grounds that the next administration should be the product of elections.

A cautious calm

Libya plunged into chaos following the 2011 overthrow and killing of Muammar Gaddafi in a NATO-backed uprising, with a myriad of armed groups and foreign powers moving to fill the power vacuum.

A cautious calm had set in by Saturday evening, an AFP correspondent reported. Flights resumed and shops re-opened on Sunday.

Bashagha had initially ruled out the use of violence to take power in Tripoli but subsequently hinted that he could resort to force.

Certain armed groups, seen as neutral in the latest crisis, returned to support Dbeibah this weekend to push back Bashagha.

The public prosecutor on Sunday asked the head of passports to issue travel bans against Bashagha, some of his ministers, and a former military intelligence official, according to a letter carried by local media.

Dbeibah said earlier Sunday he would create two committees to survey the damage from the fighting.

Negotiations to avoid bloodshed in Tripoli collapsed

Dbeibah's Government of National Unity said fighting had broken out after negotiations to avoid bloodshed in Tripoli collapsed. Bashagha denied such talks had taken place.

The UN Libya mission had called for "an immediate cessation of hostilities", deploring "indiscriminate medium and heavy shelling in civilian-populated neighborhoods."

Local media reported late Saturday that a group of pro-Bashagha forces that had been making their way to the capital from Misrata later turned back.

The fighting prompted several airlines to cancel flights to and from the capital, but flights resumed and shops reopened on Sunday morning. Educational institutions said student exams would go ahead on Monday.

On Saturday evening, Dbeibah ordered the arrest of anyone involved in the "attack on Tripoli," both civilian and military.
