A spokesman for Tunisia's interim government has announced that all banned political parties and movements will now be recognised, and declared three days of mourning for those killed.

In other developments, warning shots were fired at protesters on Thursday as they demonstrated outside the headquarters of the ruling party, continuing their calls for it to be shut down.

All the ministers in the interim government who were members of the former ruling RCD party have resigned from it, trying to distance themselves from the ousted president Ben Ali.

Meanwhile, more assets belonging to the Ben Ali family have been seized, the latest was a bank owned by Ben Ali's son-in-law.
