- Fierce fighting in Libya worst since 2011 revolution
- Militias battle for control of the airport in Tripoli
- Libya's foreign minister says the country needs foreign help
Fierce fighting raged on the outskirts of Tripoli on Sunday as militias continued to battle for control of the airport in what's being called the worst fighting in Libya since the 2011 revolution.
Clashes were concentrated around the airport, the airport road and a number of residential areas where militias have fought over the past week, residents said.
At least five people have been killed, one local official said.
The latest assaults were launched by militias from the city of Misrata and an Islamist militia umbrella group in the capital known as the "Libyan Revolutionaries Operations Room."
The airport has been under the control of militia from the Western Mountains city of Zintan for the past three years.
According to residents in different parts of Tripoli, thick plumes of black smoke rose from the direction of the airport and large blasts and gunfire echoed across the city.
Speaking by phone to Libyan television on Sunday, a spokesman for the municipal council of Qasr Bin Ghasheer, the area around the airport, said at least five people from the area had been killed in the fighting so far.
The spokesman, Mohammed Abdul Rahman, said it was hard to get an accurate casualty figure because of the intensity of fighting and limited movement in the area.
"Shells are falling on houses, children are terrified and most people have evacuated. ... Our area is suffering," he told the privately run al-Nabaa TV.
There was no official overall casualty figure for the fighting in other areas impacted over the last seven days.
At the airport, the Libyan government said 90% of planes parked there were damaged and images on social media showed various parts of the facility destroyed.
The United Nations and other international organizations and businesses have temporarily evacuated staff from Libya.
The U.S. Embassy in Tripoli said in a statement that some rounds from the fighting have hit near the compound, but all personnel "are safe and accounted for." It called for an end to the violence.
Addressing the U.N. Security Council on Thursday, Tarek Mitri, head of its mission in Libya, issued a stark warning.
"As the number of military actors mobilizing and consolidating their presence within the capital continues to grow, there is a mounting sense of a probable imminent and significant escalation in the conflict. The stakes are high for all sides," Mitri said.
"We are in the middle of an all-out confrontation between two major rival groups in the Libyan capital. That confrontation, born out of the deep political polarization, is playing itself out at the country's international airport." Mitri said.
Libya's Foreign Minister Mohamed Abdulaziz also addressed the Security Council. He warned of Libya heading toward becoming a "failed state."
Abdulaziz said Libya needed more international support and asked the United Nations to consider a "stabilization and institution-building mission."
He insisted that his country was not requesting foreign military intervention.
The Libyan Interim Government said earlier in the week it was discussing the possibility of requesting international forces.
Three years after the revolution and NATO military intervention that overthrew the Gadhafi regime, a weak central government has been outgunned by increasingly powerful militias.
The militia fighting for control of the airport from the city of Zintan and Misrata are among the most heavily armed in the country.
