CAIRO (AFP) - Egypt's Muslim Brotherhood, from which ousted president Mohamed Mursi hails, on Thursday denounced a new "police state" after the arrest of Islamist leaders and the closure of satellite channels.

The Brotherhood and its political arm the Freedom and Justice Party said they "reject the terror of the police state through its arrests of Brotherhood leaders and the closure of satellite channels".

The statement was read out to Mr Mursi's supporters gathered in Cairo's Nasr City surrounded by army vehicles, a day after the resident was overthrown by the military.
