Several Giza prosecutions referred Wednesday 109 people to misdemeanour court Saturday following their arrest for participation in 25 April protests against the Egyptian-Saudi deal to redraw their shared maritime borders.
Of the 109 referred to court, 48 were released Wednesday pending trial.
A Qasr El-Nil prosecution ordered the detention of 30 additional protesters and released 38 others.
According to the prosecution, the defendants face charges of illegally protesting, attempting to overthrow the government, rioting, disturbing public peace, and disrupting traffic.
In Alexandria, the prosecution ordered the detention of 13 protesters. In Fayoum, south of Cairo, two were released on bail of EGP 1000 each.
A number of demonstrations were held Monday to protest a recent government decision to acknowledge Saudi Arabia's sovereignty over the two Red Sea islands of Tiran and Sanafir. Police fired teargas to disperse the protests.
This was the second wave of demonstrations against the controversial deal after several thousand, including activists and politicians, rallied earlier this month in what some described as the largest protests since President Abdel-Fattah El-Sisi became president in 2014.
Egypt's interior ministry had warned ahead of Monday's protests that it would show no tolerance for attempts to “undermine the country's security,” urging people not to respond to "calls inciting chaos." President El-Sisi urged citizens a day earlier to defend the state and its institutions from "forces of evil," and to protect the country's stability.
