The raw emotion from the moment when French President Francois Hollande learned of Friday night's deadly attack as it unfolded across Paris can be seen in candid photos from the Stade de France stadium.
The president was watching France play Germany in a soccer game at the stadium -- one of six sites targeted in the attack -- when a body guard whispered into his ear.
Hollande was soon evacuated from the stadium.
Hollande blamed ISIS for the attacks, which he called "an act of war."
"And when faced with war, the country must take appropriate decisions," Hollande said Saturday. "An act committed by a terrorist army, DAESH [ISIS], against what we are, a free country that speaks together with the planet."
Hollande said the attacks were prepared and planned with outside complicity.
"An act of war prepared, planned, from outside, with outside complicity, which an investigation will establish," Hollande said. "An act of absolute barbarism. In this painful period, so serious, so decisive for our country, I appeal for unity, for togetherness, for cool-headedness, and I will address parliament in a joint session at Versailles on Monday."
In the wake of the attacks, the flag flew at half-mast on top of the Elysee palace and Hollande declared three days of mourning.
