Colombian President Alvaro Uribe has blamed the country's largest rebel group, known as the FARC, for a bomb attack on one of his electoral offices.
Authorities say Thursday's blast in the western city of Pereira targeted the office of President Uribe's Colombia First movement, just 10 days before presidential elections he is widely expected to win. The explosion damaged several buildings but caused no injuries.
The Colombian leader also blamed the rebels for a car bomb that authorities discovered and deactivated southwest of Bogota, in the city of Neiva. The president made his comments during a campaign appearance in the Manizales area.
Meanwhile, a new poll released Thursday by the University of Miami and the polling firm Zogby International shows that President Uribe is ahead of his nearest competitor, Carlos Gaviria, by a four-to-one margin. The survey also shows Mr. Uribe winning 67 percent of the vote. That would be enough to avoid a run-off election.
The poll says 85 percent of respondents gave President Uribe a positive overall approval rating. Seventy four percent approved of the job he was doing as president. If re-elected, the president pledges to continue seeking to end a decades-old insurgency by leftist rebels.
