9 injured when woman blows herself up in Tunisia's capital

Police and firemen respond after a suicide attack in the Tunisian capital, Tunis.

(CNN)A woman blew herself up Monday afternoon in the center of Tunisia's capital, Tunis, injuring at least nine people, the Tunisian interior ministry spokesperson told CNN.

The suicide bomber, a 30-year-old woman who was not previously known to authorities, detonated near a police patrol, wounding eight security personnel and one civilian, the interior ministry said in a statement.
The bomber was the only person killed in the explosion, which struck near a theater on Habib Bourguiba avenue, one of the city's central thoroughfares, at 1:55 p.m. local time (8:55 a.m. ET).
Crowds gather near the site of an explosion in the center of Tunis.
A state of emergency has been in effect for Tunisia since a spate of terror attacks rocked the country in 2015. Tunisia's presidency announced an extension of the nationwide state of emergency earlier this month, amid a tense political atmosphere.
    One of the most recent large-scale attacks to hit Tunisia came in March 2016, when scores of militants launched an assault on a military barracks near the country's border with Libya.
