The Swiss government has condemned the two bomb blasts that killed dozens of people and injured many others in Algiers.
At least one United Nations employee was among the dead and 13 were missing after car bombs hit UN and other buildings in the Algerian capital on Tuesday, according to UN officials.
Swiss President Micheline Calmy-Rey said there was no explanation or justification for the attacks.
The government added that the blasts were all the more reprehensible as they had targeted the headquarters of the UN High Commissioner for Refugees. It said it hoped the perpetrators would be brought to justice.
