The latest incidents, which took place in three towns and were reported on Sunday, were the deadliest in a wave of unrest which has lasted nearly a month.

Those taking part say they are angry at the lack of jobs for young people, but officials say the rioting is the work of a minority of violent extremists.

In the strongest sign to date authorities may be ready to make some concessions, Tunisia's Communications Minister Samir Labidia said in an interview broadcast on al Jazeera television that the government would respond to people's grievances.

He said the government was ready for a dialogue with young people.
