A loud explosion was heard outside the US embassy in the Tunisian capital Tunis, the interior ministry said.
Witnesses said a man on a motorbike blew himself up
near the diplomatic mission in the Berges du Lac district,
causing panic among pedestrians at the site.
Photos posted on local news websites showed damaged vehicles on the road outside the embassy.
The US embassy in Tunis said emergency personnel were responding to the explosion.
The local Radio Mosaique FM said that five police officers were wounded. That report could not be immediately verified. The station also reported that there may have been a second perpetrator.
Armed gunmen have targeted Tunisia in recent years, killing scores of people.
Last summer, Islamic State said it was behind three militant blasts in the capital, including one near the French embassy that killed a policeman and another that wounded five people during a security operation to detain a suspect.
