Portugal's Prime Minister Jose Socrates condemned the terrorist attacks in London on Thursday.
Portugal is prepared to cooperate with England "in any way it needs," Socrates said, adding that "democracy cannot give way to terrorism."
Portuguese President Jorge Sampaio, who is in Chile for an official visit, also conveyed his sympathies to Queen of England Elizabeth II and British Prime Minister Tony Blair, saying that the attacks were "despicable acts."
Portugal has reinforced its security measures at airports, transportation terminals, borders and embassies.
The Foreign Ministry of Portugal confirmed there are no Portuguese killed in the blasts.
