Baghdad - A US force has stormed a kindergarten in a Shi'a-dominated district in Baghdad, smashed toys, doors and windows and arrested three of its guards, the Iraqi government said on Tuesday.

US troops raided Kanari kindergarten in the Jamila area of Sadr City in Baghdad where they smashed children's toys, doors, windows and roofs, according to a statement by the media centre of the Iraqi cabinet.

"No evidence was found during the raid on the kindergarten that proves the school's involvement in terrorist acts or that it is used for storing weapons," the statement said.

The reason for the operation was not immediately known.
