South Korea's ruling party presidential candidate Park Geun-hye blasted the opposition camp Friday for accusing her of cheating and meddling in the race, saying the claims amounted to nothing but false propaganda.

"From this moment, I am declaring an all-out war on false propaganda," the 60-year-old contender of the Saenuri Party told a news conference at party headquarters. "I will firmly crush the political maneuvering, false accusations and slander that have taken over this land so that they may never re-emerge."

Park's remarks come five days before the election that is turning into an increasingly tight race between the conservative candidate and her liberal rival Moon Jae-in of the main opposition Democratic United Party (DUP).

Earlier this week, the DUP accused Park of trying to cheat during a televised presidential debate by carrying a tablet PC into the TV studio. The party has also demanded an investigation into allegations the country's main spy agency posted slanderous comments about Moon on the Internet in a bid to influence the race. (Yonhap)
