President Francois Hollande gave a live address on French TV, speaking of "unprecedented attacks in progress in Greater Paris". 

"It's a horror," he said. “Two decisions will be taken: a state of emergency will be decreed which means certain places will be closed, traffic may be banned and searches may also take place throughout the Paris region.

“The second decision I have taken is to close the borders. We must guarantee that no one can come in to commit any act. And at the same time those who may have committed crimes can be arrested if they try to leave the country.”

“I have decided that we should mobilise all the forces we have to enable the neutralisation of the terrorists and to put in place security in all areas that could be concerned.

"I have also asked for military reinforcements. They are at this moment in the Greater Paris area to ensure no further attack takes place.”

He spoke of his thoughts for the “very numerous victims, their families, the wounded” and appealed for compassion and solidarity.

France had to display "sang-froid" in responding to "terrorism", the president said.

“What the terrorists want is to scare us,” he added.
