Input: Story highlights The government deploys 5,000 security forces 
  
 Authorities arrest 30 militia members 
  
 Security checkpoints spring up around Tripoli 
  
 Earlier militia members seized the airport over a dispute with the national government 
  
 Libyan authorities arrested 30 militia members Monday after the group stormed Tripoli's airport, demanding the release of a rebel leader, the nation's labor minister said. 
  
 The government deployed 5,000 security forces to the airport area and regained control of the facility, Mustafa A. Rugibani said later in the day. 
  
 After Tarhouna militia forces seized part of the airport, armed militia members escorted passengers to cars, describing it as an evacuation of the terminal, according to local journalists who have worked with CNN in the past. 
  
 Black smoke rose from fires set in the runway area, and sporadic gunfire could be heard. 
  
 Government security checkpoints sprang up around the city on Monday amid tension over the airport standoff.

 The whereabouts of the militia leader whose release the group was demanding was unknown. 
  
 Officials at a Cabinet meeting determined that the militia leader had not been detained by the government, Rugibani said, and questioned whether word of his disappearance may have been a ruse by the militia to create a pretext for the airport standoff. 
  
 But militia members at the airport earlier Monday disputed that possibility, saying they would withdraw forces only after government officials released the rebel leader. 
  
 National Transitional Council spokesman Mohammed al-Haraizi was quoted by the official Libyan Arab News Agency as saying the NTC "condemns the kidnapping of Colonel Abu Ajaila al-Habshi, calling on the specialized authorities to investigate the incident." 
  
 Al-Haraizi said in a statement that, on Sunday evening, a force at a checkpoint into Tripoli near the airport stopped a force led by al-Habshi comprising two tanks and a number of armed vehicles, LANA said. It added that al-Habshi had been authorized by the army chief of staff to take the tanks to a base in Tripoli. 
  
 "After documents were checked, the force was allowed to move, but an unidentified force intercepted al-Habshi and kidnapped him," it said. 
  
 Al-Haraizi added that al-Habshi's men had gone to the airport believing he was being held there. 
  
 "After negotiations and convincing the group that the state does not have al-Habshi and does not know where he is, the force left the airport and it is now under the full control of the national army and security forces," he said. ||||| Armed militia members with military pick-up vehicles are seen near a plane on the tarmac of Tripoli international airport in this still image taken from video June 4, 2012.

 TRIPOLIClashes broke out between rival Libyan militias at Tripoli's international airport on Monday after gunmen drove armed pickup trucks onto the tarmac and surrounded planes, forcing the airport to cancel flights. 
  
 In a fresh challenge to the interim government's weak authority, members of the al-Awfea Brigade occupied the airport for several hours demanding the release of their leader whom they said was being held by Tripoli's security forces. 
  
 An Italian passenger who was due to fly out and later arrived at a Tripoli hotel described the situation as chaotic. 
  
 "There were about 200 of them who came into the airport, they were armed. We were waiting to board our flight and we could hear noises, people shouting," he said. 
  
 Leaders of militias which became part of the government's official security forces after the war which ousted Muammar Gaddafi said they had intervened to stop the fighting, in which they said 10 people were injured, without government leadership. 
  
 Government spokespeople were not available for comment much of the day but later said the situation had been resolved. 
  
 "The airport will resume operation within 24 hours. I heard there were some injured," government spokesman Nasser al-Manee told a late night press conference, without giving a number of those wounded in the clashes. 
  
 Weeks before a planned election, Libya's new rulers are struggling to assert control over an array of former fighters who still refuse to lay down their arms after last year's war. 
  
 STAND OFF AND NEGOTIATIONS 
  
 In a dramatic move, 60-to-70 armed militia vehicles from the al-Awfea Brigade ambushed the airport's tarmac from adjacent open fields. Surrounding the planes, the militiamen forced some passengers off the planes, a brigade fighter said. 
  
 A member of the Awfea militia, which came from the city of Tarhouna, 80 km southeast of Tripoli, said the militia believed their leader, Colonel Abu Oegeila al-Hebshi, had been detained by the Tripoli Security Committee on Sunday night. 
  
 "We are protesting his kidnapping by coming to this airport," Anas Amara said. "We have one tank outside the airport and our cars are surrounding the airplanes so they don't fly." 
  
 Violence later broke out when militia groups from Tripoli and the mountain town of Zintan arrived to try to get the Awfea militia to leave the airport. 
  
 Hakim Buhagir, leader of a Tripoli brigade, said they persuaded the Awfea fighters to hand over their weapons. 
  
 "We negotiated with them and promised them we would help find their leader within three days and they were convinced," he said. "We let them go after confiscating their heavy weapons and drafting a list of their names." 
  
 NO GOVERNMENT INTERVENTION 
  
 By nightfall former fighter brigades had helped to restore calm, but the airport remained non-operational. 
  
 Eleven planes including Austrian Airlines and Alitalia aircraft stood vacant on the tarmac, and more than 30 pickup trucks fitted with anti-aircraft weapons stood idle nearby, securing the location. 
  
 Fighters smoked and chatted near their cars, swinging their Kalashnikovs over their shoulders and sometimes firing anti-aircraft rounds into the air in celebration. 
  
 "The revolutionaries of Libya freed the airport today, not the government," Essam al-Gatous, leader of one brigade, said. 
  
 Monday's violence is the latest in a series of incidents as the North African country prepares for its first free polls for a national assembly since last year's war. 
  
 Disgruntled former fighters have held regular protests that at times have turned violent. Last month, one person was killed and several were wounded when militiamen protesting outside the prime minister's office started shooting. 
  
 In November, about 100 Libyans surrounded a Tunisian passenger aircraft at Tripoli's Mitiga airport, delaying its takeoff in an anti-government protest.

Output:
Fighting has broken out between rival militias at the Tripoli airport, witnesses tell Reuters, following a standoff in which one of the militias seized control of the facility. Militia fighters had earlier surrounded the airport, demanding the release of one of their detained leaders. The airport was forced to close, and the government eventually agreed to release the leader. But hours later the leader hadn't been released, and the militants hadn't left. Local journalists tell CNN that militia members had evacuated the terminal, escorting passengers to cars. Now other witnesses tell Reuters that they've heard gunfire inside, and seen men going in with rocket-propelled grenades.
