The coast guard station in Teboulba said the five migrants who had drowned were recovered and the others rescued in the night off the town's coast.
The migrants, most of them in their mid-20s, had set off last night on board two boats which had quickly taken on water.
Tunisian and Italian authorities have been at the forefront of rescue efforts for a flood of mainly African migrants fleeing Libya and bound for Europe on unseaworthy boats that run into trouble.
