An explosive device has been thrown into a mosque near Minneapolis in the US state of Minnesota, starting a fire but no one was injured.
About 15 to 20 people were gathered for morning prayers when the explosion occurred about 5am on Saturday, police say.
The Muslim American Society of Minnesota says the device started a fire in the imam's office at Dar Al-Farooq Islamic Center in Bloomington. Attendees extinguished the fire.
Asad Zaman, director of the society, told WCCO-TV that a witness saw someone standing by the imam's office window before the blast and also saw a truck flee the scene.
He said the imam's window was broken and a small fire bomb was thrown inside.
