Political leaders from around the world have strongly condemned the seemingly coordinated acts of terror that hit Paris on Saturday morning (AEDT).

US President Barack Obama labelled the atrocities as attacks “on all of humanity”, while Australian Prime Minister Malcolm Turnbull said “we stand shoulder to shoulder with the people of France”.

It is being reported that more than 160 people have been killed in up to seven separate shootings and bombings around the city.

More than 100 of those are believed to have died at the Cataclan concert hall, where American band Eagles of Death Metal where playing.

“Those who think that they can terrorise the people of France or the values that they stand for are wrong,” Mr Obama said in a hastily convened news conference at the White House.

“We are reminded in this time of tragedy that the bonds of liberte, egalite, fraternite, are not just the values French people share, but we share,” the president said, citing France’s national motto.

“Those go far beyond any act of terrorism or the hateful vision of those who perpetrated the crimes this evening.

“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.”

Speaking from Berlin, Mr Turnbull echoed Mr Obama’s sentiments that the attack was one against “all humanity”.

“On behalf of the Australian people, I extend our 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,” Mr Turnbull said.

“When the French people left the stadium after that shocking attack they were not cowered.

“They sang their national anthem proudly and that is how all free people should respond to these assaults.

“Freedom stands up for itself, stands up for its values in the face of terrorism.”

He said that after consulting ASIO and Australian security intelligence, the terror threat level would remain the same.

“We should be reassured, Australians should be reassured, that we have the finest security agencies in the world,” Mr Turnbull said.

“We have a government that is utterly committed to protecting the safety of Australians at home and so far as we can abroad.”

Attacks “unprecedented”: French PM

French President Francois Hollande addressed the country on TV, calling the attacks on Paris “unprecedented” in scale.

“There are several dozen dead, lots more wounded,” he said. “It’s horrific.”

“We have, on my orders, mobilised all the forces we can muster in order to neutralise the terrorist threat and secure all the affected areas.”

Australia’s foreign minister Julie Bishop said it was a “black Friday for France and the world”.

“I have already spoken to Prime Minister [Malcolm] Turnbull who is in Berlin and have shared with him all the information I have received.”

British Prime Minister David Cameron has vowed the UK will do “whatever we can to help” following the attacks.

German chancellor Angela Merkel was “deeply shocked” by the attacks, and conveyed her sympathy and solidarity, the foreign ministry in Berlin said.

United Nations Secretary-General Ban Ki-moon condemned the “despicable terrorist attacks”.

“He stands with the government and people of France,” his spokesman said.

The UN Security Council also condemned what it called “the barbaric and cowardly terrorist attacks”.

Turkish President Recep Tayyip Erdogan offered his condolences and called for “a consensus of the international community against terrorism”.

Israeli Prime Minister Benjamin Netanyahu said his country stood “shoulder to shoulder” with France in the “war against terrorism” after the attacks.
