Libya is being gripped by the worst violence since the fall of Colonel Gadhafi in 2011.
Rival militia groups are taking over large swathes of the country, fighting for power, territory and oil wealth, and successive weak governments have been unable to disarm them.
In Tripoli, two different militant groups are firing rockets and mortars at each other as they try to take control of the city's airport. Civilians are also being caught up in the fighting, with hospitals now warning they are running out of drugs.
Last week the country's foreign minister went to the U.S. to plea for international help.
But Chris Stephen, a journalist for the Guardian newspaper, says the international community does not seem eager to help.
“The feed you get from diplomats is that there are so many sides, like a sort of mosaic,” he told CNN’s Christiane Amanpour on Wednesday. “Three years ago with the rebels against Gadhafi, so it was – for NATO it was easier to know who to bomb.”
“And now the common complaint is, well, who do we bomb? We have so many militias all fighting each other. And I think that’s the thing that’s perplexing the international community.”
