Whole world shud unite and fight against such terror acts.Paris attack is an attack on entire humanity. Fundamentalism of all kinds is the worst enemy of society. Let us pray for residents of Paris."

In the worst ever string of terrorist violence in France more than 120 people were killed and over 200 injured in Paris as gunmen and bombers struck in a synchronised pattern in six locations across the city on Friday, reports said.

Among the sites the deadly attacks were carried out were  restaurants, a concert hall and the national  sports stadium. The overall toll is expected to rise.

President Francois Hollande who called it an unprecedented terrorist attack, declared a nationwide state of emergency - the first in decades - and announced the closure of France's borders .

The attacks came after France waged air strikes against Islamic State fighters in Syria and Iraq.

Reports said gunmen shot dead nearly 100 people attending a rock concert at the Bataclan music hall. Anti-terrorist commandos went for an operation, killed gunmen and rescued dozens of survivors.

Some 40 other people were killed in separate attacks, including a suicide bombing outside the national stadium where President Hollande and the  German Foreign Minister were watching a friendly soccer international.
