Election authorities aleady declared ruling party candidate Mohamed Bazoum winner of the run-off election but his rival, former president Mahamane Ousmane, has alleged fraud and also claimed victory.
Supporters of the losing candidate in Niger's presidential election have burnt tyres, threw rocks and set several buildings on fire in a third day of violent protests in the capital, Niamey.
Niger's electoral commission declared ruling party candidate Mohamed Bazoum the winner of Sunday's runoff election with 55.75 percent of the vote, but his rival, Mahamane Ousmane, a former president, has alleged fraud and claimed he won with 50.3 percent.
The election is meant to lead to the first transition from one democratically elected leader to another following four coups since independence from France in 1960.
President Mahamadou Issoufou is stepping down after two five-year terms.
The national prosecutor said late on Wednesday that several people had been arrested in the protests. Internet access has also been severely limited since Wednesday.
On Thursday, small groups of Ousmane supporters again took to the streets to lob rocks at police and national guard troops, who responded by firing tear gas.
Some protesters set private houses on fire, including that of Radio France Internationale (RFI) correspondent Moussa Kaka, a Reuters witness said.
