Indiana ? The Christian rock band MercyMe canceled a show Saturday in the St. Louis area after its tour bus collided with a car in northeastern Indiana, killing two passengers in the car and the pregnant car driver’s unborn baby.

No one in the band was seriously injured, sustaining what they described as “minor bumps and bruises.” A news story on the crash and a photo of the damaged front of the bus were posted on the band’s Web site Saturday.

“MercyMe would like to express their incredible heartache over this horrible accident,” the band said in a statement. “They are praying for the families of all who this will affect, and are asking others to please pray as well.”

Fort Wayne police Officer Liza Thomas said witnesses told police the bus was going through a green light about 1:15 a.m. when the car made a left turn in front of it. The band from the Dallas area had been in Fort Wayne for a Friday night show at Parkview Field.

“Their hearts are heavy,” the band’s statement said.
