At least five people were wounded in the Tunisian capital on Thursday when a suicide bomber blew himself up, the government said.
The Interior Ministry says the bomber targetted a police patrol in Charles de Gaulle Street in central Tunis.
It is not immediately known who was behind the attack.
Tunisia has been battling militant groups operating in remote areas near the border with Algeria since an uprising overthrew autocratic leader Zine Abidine Ben Ali in 2011.
