AKIPRESS.COM - At least nine people were injured when a 30-year-old woman blew herself up in the centre of Tunisia's capital, Tunis, the interior ministry says, BBC reports.

Describing the blast as a "terrorist explosion", the ministry said the woman had had no previous known militant background.

Eight of those hurt in the explosion on Avenue Habib Bourguiba, which runs through the middle of the city, were police officers.

No deaths have been reported.

No group has said it is behind the attack.

The attack comes at a time when the country's vital tourism industry is starting to show signs of recovery, more than three years after two deadly terror attacks decimated visitor numbers.
