UN Secretary-General Ban Ki-moon has expressed concern over rising unrest in Egypt, including deadly clashes in the capital, Cairo.
Ban stressed "the importance of peace protest."
His comments come after four people were killed in Cairo and dozens more injured nationwide on October 4 as supporters of ousted Islamist President Muhammad Morsi clashed with security forces.
Clashes broke out when hundreds of Morsi's supporters tried to converge on Cairo's Tahrir Square.
Two other rallies were held in the capital -- including one at Rabaa el-Adawiyah Mosque in the city’s east, where a pro-Morsi protest camp was violently dismantled in August.
Earlier in the day, at least two Egyptian soldiers were killed in an attack by suspected militants on an army convoy east of Cairo.
