Militias fight to control airport

Rival militias in the Libyan capital, Tripoli, fought for control of the city's main airport, leaving at least six people dead and causing the cancellation of international flights, officials said. The fighting was some of the fiercest in the capital in months and an urgent reminder of the chaos prevailing in the country: Nearly three years after the death of dictator Moammar Gadhafi, the fighters who rebelled against him remained locked in a struggle for control of territory and resources, sidelining the central government.

Seven earthquakes recorded in 14 hours

The U.S. Geological Survey has recorded seven small earthquakes shaking central Oklahoma in a span of about 14 hours. The temblors are part of an increase in earthquakes across Oklahoma, Texas and Kansas that some scientists say could be connected to the oil and gas drilling method known as hydraulic fracturing, and especially the wells in which the industry disposes of wastewater. Sunday's quakes ranged from magnitude 2.6 to 2.9.

Teachers union ready to oust Duncan

A national teachers convention called for President Obama to put Education Secretary Arne Duncan on an "improvement plan" as a prelude to replacing him. The action was taken by the American Federation of Teachers, which is meeting in Los Angeles. It represents another marker in the long-running erosion of relations between organizations that represent instructors and the Democratic president they helped to elect twice. The union stopped short of calling for Duncan's immediate departure.

Officer ambushed by suspect at drugstore

A gunman who killed a rookie officer responding to a report of an armed robbery at a drugstore never tried to rob the store and instead lay in wait for police, telling a witness to watch the news because he was "going to be famous," authorities in Jersey City said. Lawrence Campbell shot officer Melvin Santiago in the head shortly after he and his partner arrived at the Walgreens around 4 a.m. Other officers returned fire, killing Campbell.
