Egypt's ousted President Mohammed Morsi was put under detention on Thursday by the army, which launched a massive crackdown on the Muslim Brotherhood movement, arresting its senior leaders, even as a top jurist took over as the interim head of state.
The military rounded up the top leadership of the Muslim Brotherhood, arresting its supreme leader Mohammed Badie in a resort village in Marsa Matrouh, a day after the army deposed the Arab nation's first democratically elected president.
Badie was flown to Cairo on a military helicopter, media reports said quoting officials.
The former chairman of the Muslim Brotherhood, Mahdi Aakef, and his bodyguards were also arrested with four weapons in their possession, according to the state-run MENA news agency.
Arrest warrants have been issued for Badie's deputy, Khairat el-Shater, and other Brotherhead leaders on charges of inciting the killing of peaceful protesters in front of Brotherhood headquarters in Cairo's Moqattam neighbourhood.
Police are seeking another 300 members of the Muslim Brotherhood, the state-run newspaper Al-Ahram reported.
The military today confirmed that it is holding 61-year-old Morsi, but did not disclose his location.
As an uncertain new political order began to take shape in Egypt following the ouster of Muslim Brotherhood leader Morsi, Justice Adly Mahmoud Mansour - head of High Constitutional Court - took the presidential oath of office.
Mansour, 67, saluted the army, the judiciary and the police in a brief acceptance speech to rapturous applause.
He praised the protesters whose mass demonstrations spurred the military action, calling them a unifying force.
In his remarks, Justice Mansour also paid tribute to the youth of the revolution and all revolutionary forces for taking part in the "glorious day of 30 June."
"I swear by Almighty God that I will uphold the republican system, respect the constitution and the law, look after the interests of the people, protect the independence of the nation and the safety of its land," Mansour said while taking oath telecast live on state TV.
Mansour's appointment came after the military last night removed Morsi from power, a little more than a year after the Islamist leader assumed office, following massive protests against his style of functioning.
An alliance of Islamists, including ousted president Morsi's Muslim Brotherhood, called for "peaceful protests" on Friday to denounce the military's move.
The National Alliance to Support Legitimacy called for "peaceful protests on Friday in all of Egypt's provinces to denounce the military coup against legitimacy and in support of the legitimacy of President Morsi".
The statement also denounced the "killing, arrests, chaining of media freedom and the closing of TV channels," describing it as tactic of the "oppressive police state."
Muslim Brotherhood spokesman Gehad El-Haddad said the deposed president was under "house arrest" at the presidential Republican Guard headquarters in Cairo. He said some members of Morsi's inner circle have also put under house arrest.
