A leader of the Muslim Brotherhood vowed that the movement would keep up protests after Egypt's government designated it a "terrorist" group on Wednesday.
"The protests will continue, certainly," Ibrahim Munir, a member of the group's executive council who is in exile in London, told AFP, adding the move was "illegitimate".
"This is an attempt to frame the Brotherhood," Munir said of the decision, taken a day after a suicide bombing of a police headquarters in the city of Mansoura killed 15 people, in an attack claimed by an Al-Qaeda-inspired militant group.
The interim government blamed the movement for the bombing and said on Wednesday that it had "decided to declare the Muslim Brotherhood movement a terrorist organisation".
