Around seven attacks were reported around Paris with gunmen shooting people having dinner.

JOHANNESBURG - There has been international condemnation of multiple attacks in Paris, which have left at least 153 people dead.

US President Barack Obama says these are attacks against humanity while British Prime Minister David Cameron called those responsible cowards.

At least 112 people were killed by gunmen who stormed the Bataclan theatre during a concert.

Reports say the gunmen systematically executed people before the police and military stormed the building.

Around seven attacks were reported around Paris with gunmen shooting people having dinner at pavement restaurants.

Apart from the theatre, at least 40 people are reported to have been killed in a series of well-coordinated attacks.

The Stade De France also came under attack with at least two suicide bombers apparently detonating explosives.

French President Francois Hollande was attending the soccer match but was not harmed. The French football association confirmed three people died in the attack at Stade de France.

Hollande was evacuated from the stadium with the players stopping the match after the explosion and gunfire.

Hollande has closed the borders and declared a state of emergency.

"I have called the cabinet which is going to meet soon. This state of emergency will be decreed which means certain places will be closed. The second decision I've made is closing borders, we have to assure ourselves that no one can enter. This is a terrible hardship."

No one has claimed responsibility for the attacks.

This survivor says it was terrifying.

"They shot at us for like 10 to 15 minutes. It was like a blood bath, they shot at us and reloaded several times. I managed to escape because they reloaded."

The coordinated assault came as France, a founder member of the US-led coalition waging air strikes against Islamic State fighters in Syria and Iraq, was on high alert for terrorist attacks ahead of a global climate conference due to open later this month.

Terror analyst Paul Cruickshank says while no one has claimed responsibility, suspicion has fallen on the Islamic State.

"[There is] suspicion that this is some kind of Isis attack because they are increasingly getting into the business of international attacks and they've been promising and threatening exactly this kind of attack."

Meanwhile, authorities in the US have bolstered security in its biggest city and at the sight of the 911 terror attacks in New York.

The New York Police Department employed extra security at high-profile locations around the largest US city in response to the attacks in Paris.

The department maintains there are no known imminent threats, but says it is taking the precautions just in case.

Many French students and tourists in NYC gathered at Union Square to hold a vigil last night.

At the same time, the South African government says it is working closely with officials in Paris to establish whether any South Africans are among the injured or dead.

The Department of International Relations and Cooperation spokesperson Nelson Kgwete says government has joined Obama in offering condolences to the families affected.

"The South African government sends its deepest condolences to families of the deceased, to the French government and the people in general."

He says officials are working round the clock to establish if anyone from this country was harmed in the explosions.

"The South African Embassy in Paris in closely monitoring the situation, working with authorities in France and will report to Pretoria during the course of the day on any possible involvement of South African citizens in the attacks."
