At least 127 people were killed in Paris in a series of coordinated terror attacks across restaurants, a theatre and near a football stadium on Friday night. French President Francois Hollande declared a state of emergency across the country.
Hollande blamed the Islamic State for the 'act of war' on France, and Isis claimed responsibility through an official statement.
About 87 people were killed after three gunmen took hostages at the Bataclan concert hall. Explosions were also heard near the Stade de France stadium where the French football team was playing Germany. Hollande himself was reportedly at the stadium to watch the match.
Some of the accomplices of the terrorists are still said to be at large, while eight attackers have been killed.
Hollande, who called the attacks 'unprecedented' called for the closing of the country's borders.
In January, gunmen had killed nearly 20 people in Paris, including several staff members of the satirical magazine Charlie Hebdo.
While no group has claimed responsibility for the Paris attack on Friday, Twitter accounts affiliated to the Islamic State claimed that their fighters had 'paralysed' Paris on Friday the 13th.
France is a member of the US-led coalition conducting airstrikes against Isis in Syria and Iraq.
The death toll from the Paris attacks is expected to rise as several people were seriously injured.
This is said to be the worst attacks in France since World War II.
