Libya's second city Benghazi on Friday was once again the scene of protests by a crowd of over 2,000 people demanding that the remaining militias who were formed by rebels during last year's conflict that eventually ousted former dictator Gaddafi from power, should disband, else join the police or the army.

Activist and law student Bilal Bettamer was reported saying that the demands by the demonstrators at the “Benghazi will not die” rally, were to dissolve all militias and push their members into entering the the army or police force.

"And we want all pro-Gaddafi and Gaddafi-era criminals to be removed from the police and army. We want to end this stalemate between the army and militias,” he told AFP

Some of the former rebels still refuse to join the security forces as they insist that the authorities first have to purge them of remnants of the former dictatorial regime.

As helicopters and fighter jets flew over the rally at Libya's eastern city that has witnessed a series of attacks against police stations and assassinations targeting military officers, with protesters carrying banners demanding “a unified army,"”and “no more assassinations.”

The demonstrations came just a day that in this part of Libya a member of Libya’s police force, Lieutenant Awad Mohamed Al-Fakhri, was killed at his home some 50 kilometres from the city.

At the time, someone knocked at Al-Fakhri's door, and when he came out, he was shot at point blank range. The officer's mother also sustained injuries in the attack and is currently receiving treatment at the Al-Jala Hospital.

The assailant is still at large. He fled the scene of the crime in a vehicle

This part of the country has been the scene of a number of assassinations and attacks on security officials and on September 11, became the focus of the world when militants killed US ambassador Chris Stevens and three other Americans in an attack on the US consulate.
