"The President reiterated the United States' steadfast, unwavering support for the people of France, our oldest ally and friend, and reaffirmed the offer of any necessary support to the French investigation," a statement said.

"The two leaders pledged to work together, and with nations around the world, to defeat the scourge of terrorism," the White House said.

Condemning the terrorist attack, World Bank President Jim Young Kim said this kind of senseless attack is difficult to comprehend.

"We condemn violence of all kinds and the attacks in Paris are an assault on collective humanity. We send our condolences to all the families of those who have died, to the people of France and its government," Kim said in a statement.

"This kind of senseless attack is so difficult to comprehend, yet we must respond with unwavering commitment to what makes us human, coming to the aid of all around us, especially the most vulnerable," said the World Bank President in a statement.
