World leaders from Barack Obama of the United States to Ban Ki-Moon of the United Nations to Nigeria’s President Muhammadu Buhari have condemned in strong terms the Black Friday terror attacks on Paris which toll remains at 129 dead and 352 injured. Buhari described the attacks on civilians in Paris, France, as “unacceptable affront to all human values and civilized norms.”

The President, said he received the news with great shock and profound sadness, totally condemned “the barbaric attacks,” describing it as “dastardly and heinous.”

Two of the survivors of the attack inside the Concert hall, a father and his son, said the attackers were young and did not speak with any ascent, meaning they may be French nationalities with extremist Islamic views who share ties with ISIS. Except for the shout of Allahu Akbar, the attackers showed no further trace of their identities.

In a statement signed by the Special Adviser to the President on Media and Publicity, Femi Adesina, on Saturday, Buhari called for more global effort against terrorism.

The statement read: “On behalf of the government and people of the Federal Republic of Nigeria, President Buhari conveys his heartfelt sympathy to President Francois Hollande and the people of France.

“The President also extends sincere condolences to the families, relatives and friends of the unfortunate victims of the callous attacks.

“As a country which has borne the terrible human cost of terrorist attacks, Nigeria stands in full solidarity with the government and people of France as they mourn those who have sadly lost their lives in the attack on Paris.

“President Buhari calls on all peace-loving nations of the world to intensify ongoing multilateral cooperation and collaborative actions aimed at bringing the scourge of international terrorism to a speedy end for the benefit of all nations”.

The United Nations Secretary-General, Ban Ki—moon, called it “the despicable terrorist attacks carried out in various locations in and around Paris,” and demanded “the immediate release of the numerous individuals reportedly being held hostage in the Bataclan theatre.”

President Barack Obama, condemned the deadly terrorist attacks, saying the attack is not just on France but on all humanity and the universal values.

He pledged to work with France to bring those responsible to justice.

“Once again, we’ve seen an outrageous attempt to terrorise innocent civilians. This is an attack not just on Paris; it’s an attack not just on the people of France. But this is an attack on all of humanity and the universal values that we share.

“The US stands prepared and ready to provide whatever assistance that the government and people of France need to respond,” Obama said.

British Prime Minister, David Cameron, promised to offer assistance to France in this trying time.

Cameron said on Twitter: “Our thoughts and prayers are with the French people. We will do whatever we can to help.”

In his reaction, the President of China, Xi Jinping, expressed the “strongest” condemnation over the series of terror attacks in Paris.

“At the sorrowful moment of the French people, I, on behalf of the Chinese government and the Chinese people, and personally, condemn in the strongest terms the barbaric acts,” he said in a message of condolences to his French counterpart Francois Hollande.

Also speaking, the Israeli Prime Minister, Benjamin Netanyahu, said in a statement, “Israel stands shoulder to shoulder with French President Francois Hollande and with the people of France in our common battle against terrorism.”

Australian Prime Minister, Malcolm Turnbull, extended Australia’s deep sympathy to the people of France.

“Our thoughts and prayers are with them at this terrible time. But our solidarity is with them too. When the French people left the stadium after that shocking attack, they were not cowed. They sang their national anthem proudly and that is how all free people should respond to these assaults.

“In France, and Australia, all around the world, we stand shoulder to shoulder with the people of France and with all free peoples in the battle against terrorism,” Turnbull said in a statement from Berlin.

The Australian government, however, disclosed that a 19-year-old Australian woman had been injured in the attacks.

Canadian Prime Minister, Justin Trudeau, said though there was no indication that any Canadians were targeted or victims of the attacks in Paris, his government would focus on balancing security and freedom amid fear of future attacks.

“It’s too soon to jump to conclusions, but obviously governments have a responsibility to keep their citizens safe, while defending our rights and freedoms, and that balance is something the Canadian government, and indeed all governments around the world, will be focusing on,” Trudeau told reporters in Ottawa.

The German Chancellor, Angela Merkel, said she is “deeply shaken by the news and pictures that are reaching us from Paris.”

The German leader issued a statement saying her thoughts were with the victims “of the apparent terrorist attack.”

The Afghan President, Ashraf Ghani, said in a tweet to French President Francois Hollande: “I sympathise with you and your people; Afghanistan stands with France with resolve to tackle terrorism as a common enemy.”
