Three children and nine women were among 94 migrants rescued on Friday when their inflatable dinghy sank 12 nautical miles from Garabulli, east of the capital Tripoli.
Five migrants --- from Sudan, Nigeria, Chad and Egypt -- aboard the same vessel lost their lives, said navy spokesman Ayoub Kacem.
Another 91 migrants travelling in another boat were rescued in the same area, the spokesman said.
A total of 900 migrants have been intercepted or rescued by the Libyan navy since Wednesday as departures pick up due to favourable weather.
Usually in such cases the migrants are taken to detention centres pending repatriation.
Libya is a key departure point for thousands of migrants hoping to reach Europe, although hundreds drown each year attempting the crossing.
