Unidentified gunmen have shot and killed a Libyan army colonel in a drive-by shooting in the restive eastern city of Benghazi, security officials say.
"Unknown gunmen in a car with tinted windows shot and killed Colonel Mustafa al-Aguili," said a security source, who spoke on condition of anonymity, on Friday.
"The attack took place after the victim left a mosque in the Al-Hadaiek neighborhood of Benghazi, following the main Friday prayers," the source added.
Meanwhile, on Tuesday, Colonel Jelal al-Arafi escaped an assassination attempt after he discovered an improvised explosive device planted under his car in Benghazi.
On Monday, Khadija al-Ammami, director of Benghazi office for the privately-owned Libya al-Ahrar television channel, narrowly survived an assassination attempt after unidentified gunmen opened fire at her.
Benghazi, Libya's second largest city, was the birthplace of the 2011 revolution. It is largely governed by militias in the absence of unified Libyan security and military forces.
The former rebels refuse to lay down their arms, despite efforts by the central government to impose law and order.
Benghazi has been the scene of numerous attacks and political assassinations over the past year as the power struggles between militiamen have intensified.
