A powerful explosion occurred in Nashville, the capital of the US state of Tennessee, today.
"A motorhome bus exploded in the middle of the city, causing extensive damage to many buildings and spreading debris over a wide area," the Associated Press quoted the Nashville Metro Office for Emergency Management as saying.
There was no information about injuries or casualties as a result of the explosion at a time when the police cordoned off the area.
A video clip published by American media showed flames and thick smoke rising from the scene as a result of the fire caused by the explosion.
For his part, police spokesman Don Aaron said that preliminary investigations indicate that the explosion was "an intentional act."
