MINNEAPOLIS (AP) -- Minnesota health officials say three children have gotten sick from E. coli bacteria after swimming in a popular Minneapolis lake.

Two beaches at Lake Nokomis have been closed until further notice because of high bacteria levels while the state Department of Health investigates.  Park Board Superintendent Al Bangoura says it's the first report of people getting sick after swimming in Minneapolis lakes in more than two decades.

The children, all under 10 years old, are not hospitalized. Health officials say young children, the elderly and those with weakened immune systems have a higher chance of developing complications from E. coli infections.
