French police say they believe all of the attackers involved shootings and bombings in Paris are dead.

Micheal Cadot, the head of Paris police said Saturday that while all of the attackers are believed to have died, authorities are searching for possible accomplices in the attacks that left over 120 people dead.

An official says attackers who held hostages in a concert hall blew themselves up with suicide explosives belts. An official says the gunmen first sprayed cafes outside the venue with machine gunfire, then went inside the concert hall and killed more before the assault by security forces.

 

Secretary of State John Kerry is describing the attacks in Paris as ``heinous, evil'' and ``vile,'' calling them ``an assault on our common humanity.''

Kerry says the U.S. embassy in Paris is ``making every effort to account for the welfare of American citizens in the city.''

The State Department says U.S. citizens can contact 1-888-407-4747 (from the U.S.) or 202-501-4444 (from other countries) for assistance.

Kerry says the U.S. stands ready ``to provide whatever support the French government may require.''

Kerry was speaking from Vienna, where he is scheduled to attend talks Saturday on the crisis in Syria.

Vice President Joe Biden calls the attacks ``heartbreaking'' and ``outrageous'' and says, ``Such savagery can never threaten who we are.''
