Two years on, Benghazi threatens "another revolution" in Libya

BENGHAZI, Libya (Reuters) - As night fell over Benghazi, a familiar sound echoed across the eastern Libyan city - an explosion, and then gunfire. A bomb had just been thrown at a police car on patrol, injuring an officer.

It was the latest of many attacks on local security forces. Two months before, the man whose job it was to ensure Benghazi was safe, the police chief, was shot dead outside his home.
