BOGOTA, Colombia (AP) -- The army on Wednesday blamed leftist guerrillas
                  for a rare mortar attack against a Bogota military academy the night before that
                  wounded 14 people and damaged the school.

                  Officials touring the destruction at the Jose Maria Cordoba cadet school said it
                  was hit late-Tuesday with three homemade mortars made from propane gas
                  tanks. The explosive-packed tanks were launched from trucks parked in a
                  church across the street.

                  The school is in a residential neighborhood in northeast Bogota, and the injuries
                  were all to civilians. Most of the injuries were minor, and only one person was
                  hospitalized.

                  "There is no doubt in our minds that the attack was perpetrated by the
                  narcoterrorists of the FARC, who have become experts in using these kinds of
                  explosives," said Gen. Reynaldo Castellano of the army's 13th Brigade based in
                  the capital.

                  The FARC, whose full name is the Revolutionary Armed Forces of Colombia, is
                  the South American country's largest guerrilla faction. The group recently
                  pledged it would begin curtailing the use of the wildly firing mortars in civilian
                  areas.

                  The explosions knocked down one of the academy's walls, damaged homes
                  inside the grounds and a bank next door. Three unexploded mortars were also
                  found on the street.

                  The FARC carried out a similar mortar attack against the Bogota military
                  academy two years ago, wounding four people, and has used the homemade
                  explosives in other cities.

                  Prisons were targeted in two other urban attacks.

                  On Tuesday, two men dropped a 200-pound (90-kilogram) bomb from a
                  helicopter on a house located only 100 yards (meters) from a penitentiary in Cali,
                  the country's third-largest city. The bomb did not go off, and the men ditched
                  the helicopter nearby and disappeared.

                  On Monday, a group of about 150 FARC rebels used rocket-fire to knock down
                  two walls of a jail in the western city of Neiva, then stormed the prison and freed
                  19 jailed comrades.
