French President Francois Hollande announced a state of emergency after the "terrible, terrible events that's upon us" -- explosions and shootings that have left at least 100 people dead, he said at a press conference tonight.
Hollande was at the city's soccer stadium when three explosions went off there during a match against Germany. He was quickly escorted from the building and later made a public address.
"France needs to be strong, and the state needs to be strong, will be," he said.
"We also must call for everyone to be responsible. What the terrorists want is for us to be scared," he said.
The French government has since released a photo of the moment when Hollande was informed about the attacks, with the document and the face of his aide blurred before it was released.
In addition to ordering a state of emergency, Hollande said that he decided to close the country's borders "to make sure that those who've committed these crimes can be stopped if they're trying to leave this territory."
Roads within were also going to be closed per Hollande's instructions.
President Obama has also made a statement of the attacks, calling it a "heartbreaking situation."
The two heads of state spoke earlier today about the upcoming climate change summit that was due to take place in Paris, where more than 120 heads of state were expected to attend, at the end of the month.
Hollande was due to attend the G20 summit in Turkey on Monday but he has since confirmed that he will not be attending.
