Army ousts Egypt's President Morsi
Egypt's army has removed President Mohammed Morsi from power, suspended the constitution and pledged new elections following mass protests, BBC reported.
The army chief announced the move in a TV address. The head of the constitutional court is expected to be sworn in as interim leader on Thursday.
Mr Morsi's supporters denounced the move as a military coup and said he was being held in detention.
His opponents celebrated through the night in Cairo's Tahrir Square.
But officials from Mr Morsi's Muslim Brotherhood said its main rally in Cairo had come under attack by armed assailants and there were reports of deadly clashes elsewhere.
US President Barack Obama said he was "deeply concerned" by the latest turn of events and called for a swift return to civilian rule.
