4. Libya's Interim Government
The U.S. State Department said the stability of Libya's current interim government is uncertain. Elections were held earlier this year, but "political jockeying continues over where and when to seat the parliament," said the state department.
According to the AP, rival militias forced a week-long closure of gas stations and government offices. In May fighting broke out between rival factions near Benghazi.
The Libyan Council of Representatives is scheduled to convene on Aug. 4.
