LIMA, Peru - Thousands joined in marches across Peru on Tuesday to oppose the presidential candidacy of Keiko Fujimori just days before her runoff contest against another pro-business conservative, Pedro Kuczynski.

Fujimori's critics view her as a threat to democracy, pointing to her father, former President Alberto Fujimori. He is in prison for authorizing death squads and corruption during his decade in power as an authoritarian leader in the 1990s.

Keiko Fujimori has sought to counter her critics by vowing not to revive the hard-line methods of her father, who is still popular with many rural Peruvians for defeating the Maoist-inspired Shining Path rebels.

Fujimori easily led the initial round of the April 10 presidential ballot. Kuczynski, a former World Bank economist, finished second to earn the other spot in Sunday's runoff election.
