A group of children just barely escaped a tornado that caused heavy damage to a South Dakota church.

Yesterday's twister struck while the kids were attending Sunday school at Zion Lutheran Church in Delmont, about 90 miles west of Sioux Falls.

The warning sirens sounded just in time, allowing the children to be rushed into the basement before the tornado tore the top off of the church. 

No one was hurt at the nearly 100-year-old church.

Authorities reported nine injuries and 20-25 structures destroyed in Delmont, including the local fire house. None of the injuries are said to be serious. 

As of this morning, the town was without power, water and telephone service.

Meantime in western parts of South Dakota, residents are digging out from more than a foot of snow.
