More than 120 people have been killed and more than 350 wounded in a series of coordinated terror attacks in Paris.

The attacks prompted French President Francois Hollande to order a state of emergency and the closure of the entire nation's borders.

Police in Belgium made three arrests Saturday at the border in connection with the attacks.

One of the men arrested was a French national, as was one of the eight terrorists who died in the attacks.

Hollande called the attacks an “act of war” and blamed ISIS.

He promised that "France will be merciless towards these barbarians from Daesh," using a derogatory Arab acronym for the Islamic State.

ISIS claimed responsibility for the attacks on an encrypted messaging account, calling them "the first of the storm" and mocking France as a “capital of prostitution and obscenity.”

A Syrian passport was found on the body of a suicide bomber at the Paris stadium.

French authorities are investigating the attacks and urging any witnesses to come forward.
