TRIPOLI/BENGHAZI, Libya—A warplane attacked Tripoli’s only functioning airport on April 8 as eastern forces advancing on the Libyan capital disregarded international appeals for a truce in the latest of a cycle of warfare since Muammar Gaddafi’s fall in 2011.
Casualties were mounting in fighting that also threatens to disrupt oil supplies, fuel migration to Europe and wreck U.N. plans for an election to end rivalries between parallel administrations in the country’s east and west.
