British PM says stands shoulder to shoulder with France after Nice attack

British Prime Minister Theresa May said here Friday that Britain will stand shoulder to shoulder with France after at least 84 people were killed in an attack Thursday evening in Nice.

May said she was "shocked and saddened" by the "horrifying attack" in Nice, adding Britain is investigating if there's any Britons involved in the attack.

"Our hearts go out to the French people, and to all those who have lost loved ones or been injured. While the full picture is still emerging, it seems that at least 80 people are feared dead and many others have been injured. These were innocent victims enjoying a national celebration with their friends and families," she said.

May said an ambassador is travelling to Nice on Friday with consular staff and they will help people affected.

A COBR meeting involving senior officials will be held by the British government on Friday after the Nice attack.

She said if it is confirmed as being a terrorist attack, efforts must be redoubled to stand up to these "brutal murderers".

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

London Mayor Sadiq Khan said Friday morning that he would review the safety measures to do everything possible to keep Londoners safe.

British Foreign Secretary Boris Johnson said earlier that at least one Briton was injured in the attack in Nice. The Foreign Office also issued an alert urging British people in Nice to follow the instructions of the French authorities.

The British Union Flag and French Tricolour are flying at half-mast over 10 Downing Street as a mark of respect following the attack.

At 22:30 (2030 GMT) Thursday night local time, a truck drove at high speed into a crowd who gathered on the promenade in Nice, France to watch a fireworks show marking the French national day, killing at least 84 people and injured many. Endit
