Some official sources had suggested that those killed were involved in arms and drug dealing.
 
However, Assarih, a Tunisian newspaper, said the dead were involved in terrorist activities. The latest incident took place in Soliman near the town of Nabeul.

In last month's clash, two gang members were killed and two policemen wounded in the Tunis suburb of Hammam-lif.

The authorities deployed hundreds of paramilitary police to guard crossroads and search orange groves outside Tunis over the past 13 days, residents said.
