Excerpts of a report by the internal affairs committee of the General National Congress did not give comparative figures for deaths in 2012 nor data on crimes committed.
Since a NATO-backed uprising ousted and killed Moamer Kadhafi in 2011, Libya's authorities have struggled in vain to contain lawlessness, much of it perpetrated by former militias who fought to overthrow the long-time dictator.
There are almost daily reports of violence across large swathes of the country where ex-rebels rule, including Al-Qaeda-inspired groups which have taken advantage of the lawlessness.
Even Prime Minister Ali Zeidan was kidnapped by militiamen last year before being released several hours later.

In its report, the committee said "crime has become a profession and a source of income in the absence of an effective police force, despite their being 250,000 policemen."
It noted that Libya has one policeman for every 30 people, saying that number is not high enough.
The committee also highlighted the fact that the government has integrated into the security forces only 29.6 per cent of the estimated 170,000 militiamen who fought the Kadhafi regime. Many of the rest are refusing to give up their weapons.
The difficulty of the job is highlighted by the fact that Libya has had four interior ministers since Kadhafi's overthrow, with the last two having quit.
