MINNEAPOLIS (AP) -

Students are back in class after a boiler explosion forced the evacuation of an elementary school in Minneapolis.

School officials say the boiler exploded around 12:30 p.m. Thursday at Lake Harriet Upper Elementary School.

KSTP-TV reports students were evacuated to a nearby fire station, and have now returned to class.

No one was hurt.

Work is being done to either repair the boiler or see if a secondary boiler can be used.
