Although the jihadist group Islamic State (ISIS) praised the attack on public places in Paris which killed over 100 people, and the attackers were heard shouting "Allahu Akbar" while killing innocent individuals, US President Barack Obama still made no mention of the word "Islam" in his statement about the devastating terrorist attack on France.

In a brief address to the nation on Friday, the American leader described the terror attack at the French capital as a "heartbreaking situation."

Obama also expressed sympathy to France, which was placed under a state of emergency after terrorists opened fire at concertgoers and detonated bombs at a football stadium.

"Obviously those of us here in the United States know what it's like. We've gone through these kinds of episodes ourselves," Obama said in his address, as quoted by WND.com.

"I'm sure that in the days ahead we'll learn more about exactly what happened, and my teams will make sure that we are in communication with the press to provide you accurate information. I don't want to speculate at this point in terms of who was responsible for this," he added.

Obama condemned actions taken "to terrorise innocent civilians." He stopped short of blaming the Paris attack to any particular Islamic element or extremist groups.

"We're going to do whatever it takes to work with the French people and with nations around the world to bring these terrorists to justice, and to go after any terrorist networks that go after our people," Obama said.

"Until we know from French officials that the situation is under control, and we have more information about it, I don't want to speculate," he added.

Just before the Paris attack, the U.S. President said that the ISIS has already been "contained." He also said that the extremist group is not gaining strength at this point.
