Rapidly escalating violence is limiting civilians' ability to travel in and out of Libya's capital. An airstrike on Tripoli's international airport Monday and other recent clashes have now forced some 3,400 people to leave their homes, according to the U.N.'s Humanitarian Affairs office.
"Clashes with heavy weapons are affecting residential areas, and an unknown additional number of civilians are unable to flee these locations," the office said Monday.
The fighting intensified over the weekend, as soldiers loyal to Khalifa Haftar — the former army chief who now leads the Libyan National Army — neared the capital. Haftar, who is aligned with Gaddafi regime loyalists, has amassed power and resources in eastern Libya. Last week, he launched an offensive to the west, aiming to take control of the capital.
The death toll from the clashes has risen to at least 51, the Associated Press reports — citing a figure that includes both civilian and military casualties.
Relief workers are warning of a wide range of potential risks, from emergency aid that's been blocked by the fighting to possible long-term damage to the city's infrastructure. It's the latest sign of renewed instability in Libya, where conflict and political uncertainty have lingered since 2011.
