The National Council for Human Rights (NCHR) issued a statement Sunday saying that 89 violations were recorded during the first day of voting in the second stage of Egypt's parliamentary elections.
Second stage voting is taking place in 12,946 polling stations in 13 governorates.
"Among the most significant violations was the delay in opening many polling stations in different governorates (Cairo, Ismailiya, Qalioubiya, Gharbiya, Kafr El-Sheikh), and there have been 13 complaints about electoral bribes in Cairo, Daqahliya and Gharbiya," the statement read.
The statement also said that there were 16 complaints about illegal campaigning near polling stations in governorates including Cairo, Kafr El-Sheikh, Qalioubiya and Gharbiya.
Also in greater Cairo, the council monitored a polling station were a supervising judge used a single ballot box for both individual and list-based candidates, which violates regulations issued by the High Elections Committee.
The NCHR said it will continue monitoring the electoral process through the second day of voting.
Egypt opened polling stations for the second day on Monday in Cairo and 12 other governorates for the second stage of the parliamentary elections.
Voting hours are between 9am and 9pm, and public sector employees have been given a half-day off to allow time for voting.
Monday marks the last day before run-offs on 1 December and 2 December.
The last parliamentary elections held in Egypt came months after the toppling of president Hosni Mubarak in February 2011 amid revolutionary fervour, yielding a turnout of 62 percent in the first round.
Egypt has been without a parliament since the 2011 chamber, dominated by Islamists, was dissolved by a court ruling in June 2012.
