"The motorcade of Colonel Abdallah al-Saati, head of the joint security room and military governor of Benghazi, was attacked as he passed through the Al-Hadeq area, leaving one dead and one seriously wounded from his entourage," said security forces spokesman Colonel Abdallah al-Zaidi.
Benghazi's joint security room is a body grouping together all the different security bodies operating in the eastern city.
"Explosives experts are currently combing the neighbourhood to determine how the convoy was attacked and the amount of explosives used in this blast, which was heard in most areas of the city," said Zaidi.
Eastern Libya, and particularly the city of Benghazi, has been hit by a wave of attacks mostly targeting security officials since the fall of longterm dictator Moamer Kadhafi in October 2011.
