Egyptians gathered on Friday, September 20 demanding the departure of Egyptian President Abdel Fattah Sissi.
Human Rights Watch (HRW) on Saturday called on Egyptian authorities to protect the right to peaceful protest, one day after rare demonstrations erupted against Egyptian President Abdel-Fattah al-Sisi. El-Sisi has called the allegations "lies and slander".
"If el-Sisi does not announce his resignation by Thursday, then the Egyptian people will come out to the squares on Friday in protest", Ali said in a video posted on Tuesday.
"By just saying to Sisi in the street "get out" in a crowd chanting, we are in front of a pivotal moment in the face of the rule of the military gang", Amr Bakly, an Egyptian blogger and political activist, said of the protests in a post on Twitter.
Egyptian authorities did not immediately comment on the protests.
Ahead of the protests, critics used social media to decry corruption in the Sisi regime and the ruling class.
He confirmed that they didn't receive any reports of casualties by live or rubber bullets.
"The authorities should recognise that the world is watching and take all necessary steps to avoid a repetition of past atrocities".
"Everyone must obey and promise this", he said in the message, according to Israel's Ynet news site.
Demonstrations also reportedly took place elsewhere around the country.
Sisis flew to NY on Friday night where he is scheduled to address the United Nations General Assembly next week.
Egyptians quickly took to social media to criticise Adib, a vocal backer of Mubarak during the 2011 revolution, for dismissing the protesters as "people against the country".
Hamas, which has historic links to Egypt's Muslim Brotherhood, enjoyed warm relations with Egyptian president Mohammed Morsi, a top Brotherhood figure who was overthrown by the military after a divisive year in power. "The police didn't use lethal force." he said.
At least 74 people were arrested, a security source told AFP, with plain clothed police patrolling sidestreets of downtown Cairo.
The protesters were responding to a call by a self-exiled businessman who claimed corruption by the military and government without providing evidence. Egypt is recovering and facing challenges with insistence on a daily basis.
