At least six people died after tornadoes and severe storms tore through parts of Tennessee on Saturday.

Buildings were reduced to rubble and communities were plunged into blackouts when extreme weather battered parts of the southern US state.

Three of the deaths were reported in a northern suburb of Nashville, the states capital.

Two adults and a child were killed in the city of Clarksville, around 50 miles (80.4km) to the north-west.

Another 23 people in the surrounding area have been hospitalised, the Montgomery County government said.

Wes Golding, the countys mayor, said: This is a sad day for our community. We are praying for those who are injured, lost loved ones, and lost their homes.

As of 21:30 local time (0330 GMT Sunday), almost 60,000 people were without power, according to tracking sitepoweroutage.us.

Videos posted on social media showed overturned cars and uprooted trees littering streets lined by ruined buildings.

Footage captured the funnels of large tornadoes making contact with the ground and bright flashes of lightning across the sky.
