 On Thursday, members of the Third Force militia loyal to the UN-backed government of national accord (GNA) in Tripoli attacked the base used by Haftar’s self-proclaimed Libyan National Army (LNA), according to military sources. 
  
 An LNA spokesman, Ahmad al-Mesmari, said that the victims included civilians who worked at the Brak al-Shati airbase or who were in the nearby area. “The soldiers were returning from a military parade. They weren’t armed. Most of them were executed,” he said. 
  
 The GNA said that a commission of inquiry had been set up to investigate the attack. It said it had decided to suspend its defence minister, Al-Mahdi al-Barghati, and the head of the Third Force from their duties until those responsible were identified. 
  
 The GNA and defence ministry condemned the assault and said they had not ordered any such action. 
  
 The unity government, the rival administration in eastern Libya and their respective backers are battling for influence in the north African country, which has been wracked by chaos since the fall of dictator Muammar Gaddafi in 2011. 
  
 The LNA does not recognise the authority of the GNA and instead supports the rival authorities based in the east. 
  
 The UN envoy to Libya voiced alarm at reports of the attack on the base, 650km (400 miles) south of Tripoli. “I am outraged by reports of significant numbers of fatalities, including civilians and by reports that summary executions may have taken place,” the UN envoy, Martin Kobler, said. 
  
 Britain’s ambassador to Libya, Peter Millett, also denounced the assault. “Disgusted by attack on Brak al-Shati & reports of mass executions. Perpetrators must be brought to justice,” he wrote on Twitter. 
  
 The incident at the base in Wadi al-Shati district took place a month after an attack by the LNA on the Tamenhant airbase controlled by the Third Force near the south’s main city of Sebha.

 That attack was called off after a reconciliation meeting between Haftar and the head of the unity government, Fayez al-Sarraj, in Abu Dhabi on 2 May. 
  
 The speaker of the eastern-based parliament, which is supported by the LNA, accused the Misrata-based Third Force of a “serious breach of the truce agreement reached in Abu Dhabi”. Aguila Saleh said there were a “number of martyrs” in LNA ranks, without giving a figure. 
  
 The speaker said he had given orders for the armed forces “to take the measures necessary to respond to the assault and defend the south and cleanse it of all outlaw militias”. 
  
 In Tripoli, the GNA called for an immediate ceasefire in the south where tribes and militias vie for control of lucrative smuggling routes with neighbouring Chad, Niger and Sudan. “We hope reason will prevail and that the escalation and provocation will stop,” it said. 
  
 The unity government’s defence ministry laid the blame on “those who started bombing Tamenhant base with warplanes and tanks,” referring to Haftar’s forces. 
  
 Elsewhere on Friday a pro-Haftar tribal chief, Sheikh Ibrayek Alwati, and five other people including a child were killed in a car bombing outside a mosque in the eastern city of Slouq, according to medical and security sources. ||||| Image copyright AFP Image caption Many of those killed were from the Libyan National Army, seen in action in this file photo 
  
 Reports suggest as many as 140 people, including civilians, may have died in an attack on an airbase in Libya. 
  
 It was originally thought 60 people died when a government-allied militia tried to take over the Brak al-Shati base on Thursday. 
  
 The UN-backed government's defence minister and the commander of the militia have both been suspended pending an investigation. 
  
 The prime minister's office has denied ordering the attack. 
  
 A militia spokesman said they had "liberated the base and destroyed all the forces inside". 
  
 The town's mayor said some aircraft had been set ablaze. 
  
 Most of the dead were soldiers of the self-proclaimed Libyan National Army (LNA), an alliance in the east of the country which does not recognise the government in the capital, Tripoli. That force has been in control of the airbase since December. 
  
 Its spokesman gave the new death toll of 140. 
  
 "The soldiers were returning from a military parade. They weren't armed. Most of them were executed," he said. 
  
 The UN's envoy to Libya, Martin Kobler, said he was "outraged" by reports of summary executions. 
  
 The attack breached an informal truce between the rival forces that was reached earlier this month when the LNA's commander, General Khalifa Haftar, met the UN-backed Prime Minister Fayez al-Sarraj. 
  
 The Tripoli government has set up an investigative committee to present its findings to the prime minister within 15 days. |||||
A:
An official in Libya says at least 140 people—including civilians—were killed in a strike on the Brak al-Shati airbase, more than doubling the original count from the attack Thursday, the BBC reports. According to the Guardian, the base was attacked by the Third Force militia, which is loyal to the UN-backed Libyan government. A spokesperson for the Third Force says they "liberated the base and destroyed all the forces inside." Brak al-Shati had been under the control of the Libyan National Army, a group that doesn't recognize the government and is loyal to military strongman Khalifa Haftar, since December. An LNA spokesperson says most of the 140 casualties were unarmed soldiers returning from a military parade, adding most of them were "executed." The spokesperson says the dead also include civilians working on the base or in the vicinity. The UN-backed Libyan government condemned the attack, which it denied ordering. It says it has suspended the defense minister and the Third Force's commander pending an investigation. Martin Kobler, UN envoy to Libya, says the "unprovoked attack" could amount to a war crime, Al Jazeera reports. “I am outraged by reports of significant numbers of fatalities, including civilians and by reports that summary executions may have taken place,” Kobler says. The attack may also have breached a truce between Haftar and the government reached on May 2.
