Cairo : Egyptian President Abdel-Fattah el-Sissi was sworn in for a second four-year term today after being re-elected in a vote earlier this year in which he faced no serious challengers. El-Sissi took the oath of office before parliament amid tight security enforced throughout Cairo. After the oath, artillery delivered a celebratory 21-gun salute. In an address to the packed chamber, el-Sissi vowed to continue working to restore stability, revive the economy and combat the insurgency in the northern Sinai Peninsula.
