CAIRO, Aug. 17 (Xinhua) -- Egypt's security forces on Saturday exchanged fire with loyalists of ousted President Mohamed Morsi, a Xinhua correspondent near the mosque said.
The loyalists of Morsi ascended a minaret of a mosque in downtown Cairo, the correspondent said.
Earlier, security forces partially evacuated Al-Fatah Mosque in Ramses Square, where a large number of Morsi's loyalists had been taking shelter since early Friday.
At least 173 people were killed and 1,330 others injured in overnight clashes across Egypt between the supporters of Morsi and security forces, a cabinet spokesman said Saturday.
Early Saturday, the interior ministry said some 1,118 Morsi's supporters had been during the overnight clashes.
On Friday, Morsi's supporters held marches across the country to protest Wednesday's dispersal operation against their sit-ins, which left at least 578 killed and over 4,200 injured.
