CAIRO, Jan. 26 (Xinhua) -- The Egyptian police on Saturday arrested as many as 1,079 supporters of ousted president Mohamed Morsi over charges of riots and attempted violence, the country's interior ministry said in a statement early Sunday.
Some of the rioters possessed machine guns and Molotov cocktails, according to the ministry.
The arrests came during Saturday's mass celebrations on the third anniversary of Jan. 25 uprising that toppled ex-president Hosni Mubarak.
The statement said that Morsi's supporters, mostly from the Muslim Brotherhood and their affiliates, attempted to ruin the celebrations "by staging marches to block traffic, shouting hostile slogans and inciting riots."
On Saturday, at least 29 people were killed and around 170 others were injured during clashes between security forces and pro-Morsi protesters as well as some anti-government activists.
Similar clashes on Friday left 15 people dead and several others injured.
