Two more police stations were attacked in Libya's eastern city of Benghazi in the early hours of Sunday morning, the local council said, after two others were bombed on Friday.

The attacks are the latest signs of insecurity in Libya's second city, birthplace of the uprising that toppled Muammar Gaddafi in 2011. The recent violence against diplomats, military and police includes an attack in September that killed the U.S. ambassador and three other Americans.
