Egypt's dramatic military coup has been completed after an interim President was sworn in.
Less than 24 hours after President Mohamed Morsi was ousted amid widespread protests against his regime, Adly Mansour, the head of the constitutional court, took over.
Officials then announced they had arrested the Supreme Leader of the Muslim Brotherhood, Morsi's party, Sky News reported.
And arrest warrants were issued for up to 300 Muslim Brotherhood members, The Guardian reported.
Key Muslim Brotherhood bases were raised and closed down, as the military tightened its grip on the country.
Speaking to Channel 4 News, the new president said: "I did not come to power through election, but through the trust of the revolutionaries in the square."
He called on Egyptians to "be one body," and said "we have had enough of division."
"We require from all parties, left and right to mobilize theirs forces, to build this nation," he added.
The decision to remove Egypt's first democratically-elected President has alarmed the West.
Foreign Secretary William Hague warned it could become a precedent and called for a swift return to democracy.
Hague said he had spoken to Egypt's foreign minister who had assured him that there would be early elections to choose a new president.

"It is the problem with a military intervention, of course, that it is a precedent for the future. If this can happen to one elected president, it can happen to another," he said.
"That's why it is so important to entrench democratic institutions and for political leaders - for all their sakes and the sake of their country - to work on this together to find the compromises they haven't been able to make in Egypt over the last year."
