Britain and France 'united' in fight against ISIS 'death cult'

Britain and France have agreed to increase counter-terrorism cooperation following the Paris attacks, David Cameron and Francois Hollande announced Monday morning.

Speaking about a "shared threat", the British Prime Minister told a press conference at the Elysee Palace that the UK would "do all in our power to help our friend and ally France".

"Nous sommes solidaires avec vous," Cameron said, meaning "We are united with you".

President Hollande, who also addressed the press conference, told journalists that France would intensify its air strikes to cause the greatest damage possible to ISIS.
