Terror attacks in the Algerian capital has left as many as 62 people dead.
Two United Nations staffers are among the dead, and at least 10 more are missing after a pair of car bombs exploded 10 minutes apart.
The explosions appear to be targeted attacks on government and UN buildings.
A UN spokeswoman spoke out against the terror attack during a news conference in New York on Dec. 11.
"This was a cowardly strike against civilian officials serving humanity's highest ideals under the UN banner, unjustifiable by even the most barbaric political standard," said Marie Okabe, the United Nations deputy spokeswoman.
So far no group has claimed responsibility for the blasts.
