The Egyptian parliament voted unanimously on Tuesday in favour of imposing a state of emergency declared by President Abdel-Fattah El-Sisi on Sunday.
The measure comes following two deadly suicide bombings that hit Egypt's St George Cathedral in Tanta and St Mark's Cathedral in Alexandria on Palm Sunday, killing 46 and injuring dozens more during prayer services.
The state of emergency is now in effect following parliament's approval.
According to the Egyptian constitution, any state of emergency must be confirmed in parliament by majority vote within seven days of its declaration by the president.
