Colombian security forces say they are investigating an alleged attempt to kill President Alvaro Uribe after an explosion in a building close to an airport, shortly before the president's arrival there.
Officials say the blast occurred Thursday in the city Neiva about 230 kilometers south of Bogota. They found what appeared to be a homemade rocket and two grenades.
The officials believe the devices exploded prematurely and suspect the rebel Revolutionary Armed Forces of Colombia, FARC, may be behind the alleged plot.
President Uribe later arrived safely at the airport.
With the support of the United States, Mr. Uribe is waging a campaign against armed insurgents in Colombia.Some information for this report provided by AP and Reuters.
