Prime Minister Theresa May has said Britain must redouble its efforts to defeat "brutal" terrorist "murderers" after the "horrifying" attack in Nice, France, and has called a meeting of senior officials in the Government's emergency Cobra committee.

I am shocked and saddened by the horrifying attack in Nice last night.

Our hearts go out to the French people and all those who have lost loved ones or been injured," she said.

While the full picture is still emerging, it seems that at least 80 people are feared dead and many others have been injured.

It was innocent victims enjoying a national celebration with their friends and families.

We are working urgently to establish whether any British nationals were caught up in the attack.

Our ambassador is travelling to Nice today with consular staff and they will be doing all they can to help anyone affected.

I have asked my deputy national security adviser to chair a Cobra meeting of senior officials to review what we know and what we can do to help and I will speak to President Hollande today and make clear that the United Kingdom stands shoulder to shoulder with France today as we have done so often in the past.

If, as we fear, this was a terrorist attack then we must redouble our efforts to defeat these brutal murderers who want to destroy our way of life.

We must work with France and our partners around the world to stand up for our values and for our freedom.

The threat level here in the UK is already at severe that means that a terror attack is highly likely senior officials today will be reviewing what more we can do to ascertain if there is any further action we need to take but the police.

The government is already making more funding av for the security services which will enable them to increase efforts it is also making more funding available to the police.

We always look at these issues we have been living with a severe threat level for some time now but today our thoughts must be with all those in France.
