Police in Argentina say there have been small bomb explosions and anti-United States leaflets scattered at two branches of a U.S.-based bank and a video store in the suburbs of Buenos Aires.

The explosions early Thursday started a fire at the video store, but officials said no injuries were reported. Pamphlets denouncing President Bush were found in the debris following the explosions.

Police are investigating.

The White House announced Wednesday that Mr. Bush will visit Argentina, as well as Brazil and Panama, next month when he attends the Summit of the Americas in Argentina's Mar del Plata. The summit brings together 34 leaders of democratic nations from North, Central and South America.
