Peruvian presidential candidate Keiko Fujimori starred Saturday in a protest rally in the historic center of Lima along with thousands of her supporters alleging fraud in last weekend's polls, while expected winner Pedro Castillo called for people to remain calm and not to fall for "provocation."

Fujimori addressed her supporters from a platform on a truck that displayed a large slogan that read "democracy yes, communism, no."

"This is the most democratic expression of what 50 percent of Peruvians represent," the candidate of the right-wing Fuerza Popular party said.

She reiterated that since last Monday her party began to receive complaints from citizens of "hundreds of irregularities" allegedly committed during the election, and for that reason, her party presented more than 800 requests for the annulment of votes before the National Jury of Elections (JNE).
