At least four people were killed in a suicide bombing at a Libyan army base in the eastern city of Benghazi on Tuesday, according to a security source.

Islamist militants and army forces have been clashing regularly in the city, Reuters reported. However, suicide attacks have occurred rarely amid the turmoil that has come after the toppling of leader Muammar Gaddafi.
