Paris Attack: 140 killed in multiple strikes, France declared emergency

Gunmen and bombers attacked Restaurants, a concert hall and a sports stadium in seven near-simultaneous attacks at locations in Paris on Friday, killing at least 140 people, in what a shaken president Francois Hollande called an unprecedented terror attack.

A Paris city hall officially said gunmen systematically slaughter nearly 100 people attending a rock concert at the Bataclan music hall. Anti-terrorist commandos eventually launched an assault on the building, killed the gunmen and rescued dozens of shocked survivors.

Some 40 other people were killed in up to five other attacks in the Paris region, a city hall official said, including an apartment double suicide bombing outside the national stadium where President Francois Hollande and the German Foreign Minister were watching a friendly soccer international.

Paris Public Prosecutor Francois Molins said five assailants have been "neutralized".

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

After being whisked from the soccer stadium near the blast, the President Hollande declared Nationwide state of emergency - the first in decades and announced the closure of France's border to stop perpetrators escaping. The Paris metro railway was closed and schools, universities and municipal buildings are ordered to stay shut on Saturday. However some rail and air services are expected to run.

"This is horror", the visibly shaken President said in a midnight television address to the nation before charging an emergency cabinet meeting.

All emergency services were mobilised, police leave was cancelled, 1500 army reinforcements were drafted into the Paris region and hospitals recalled staff to cope with the casualties.

It is still unclear weather any gunmen were still on the loose.

Radio stations broadcast warnings to Parisians to stay home and leave the streets and urged residents to give shelter to anyone caught out in the street.

Two explosions were heard near the Stade de France in the northern suburb of Saint-Denis, where France-Germany friendly soccer match was being played. The witness said that one of the detonations blew people into the air outside a McDonald's restaurant opposite the stadium.

The match continued until the end but penic broke out in the crowd, as rumours of the attack spread and spectators were held in the stadium and assembled simultaneously on the pich.

The police helicopter circled the stadium as President Hollande was rushed back to the interior ministry to deal with the situation.

The deadliest attack was on the Bataclan, a popular concert venue where the California rock group Eagles of Death Metal was preforming. The concert hall is just a few hundred meters from the former offices of the Satirical weakly Charlie Habdo, which was the target of the deadly attack by Islamist gunmen in January.

Witnesses in the hall heard the gunmen shout Islamic slogans and slogans condemning France's role in Seriya.

"We know where these attacks come from", Hollande said without naming and individual group. "There are indeed good reasons to be afraid."

France has been on high alert ever since the attacks on Charlie Habdo newspaper and a Kosher supermarket in Paris in January,  killing 18 people.
