An emotional Alize Cornet rallied to beat world number five Agnieszka Radwanska 6-4, 2-6, 7-5 at the Hopman Cup in Perth on Friday, the Frenchwoman spurred by her determination to win for the victims of the Charlie Hebdo attack in Paris.

Wednesday's killing of 12 people at the offices of the French satirical magazine has triggered a global outpouring of shock and grief and the world number 18 arrived at the Perth Arena court with the message "JE SUIS CHARLIE" (I am Charlie) taped to her bag.

"I learned about it during (Hopman Cup team mate) Benoit Paire's singles match two days ago. I was horrified. I was so shocked and very emotional about it," Cornet told reporters after what she described as one of her best ever wins.

"These people that they killed, it is kind of the patrimony of France. It is the people that you know so well. You have the feeling they are part of your family.

"Twelve people dead and all this violence... it touches the whole world and the whole humanity, and we really have to be strong.
