Meanwhile the prime minister, Pedro Passos Coelho, was among those who visited France's embassy in Lisbon to sign a book of condolences, in which he transcribed a text expressing his "total solidarity" with France's authorities and people, and "deep condolences" for the families of the victims.


The text of the parliamentary resolution expresses consternation and sadness at the events in Paris as well as its solidarity with the families of the victims and the surviving staff of 'Charlie Hebdo'.


After the vote, members of parliament observed a one-minute silence.


"Paris is now the place where we all live," the resolution declares. "The place where a new impetus is generated, an impetus of will for an unyielding and daily struggle for dignity and rights, for freedom and democracy."


It stressed that although violence and attacked "our newspapers, those places where freedom is exercised and democracy pulses", this "horror" will not prompt the betrayal of democracy.


"Terror can never be understood as owing to ethnic or religious groups, to cultural groups, to nations or regions," it continues. "Freedom of the press is a condition for the freedom of all, for the public use of reason, for the freedom of being, of acting ... and intervening in the world."


Police in France continue to attempt to capture the three men suspected of having carried out Wednesday's attack, which has been followed by several others.
