Key Paris attacks suspect Salah Abdeslam will oppose his transfer to France and has been formally charged by the Belgian examining magistrate in connection with the November massacre, his lawyer said Saturday.

"He will refuse his extradition at this stage," Sven Mary told reporters at federal police headquarters in Brussels, adding that his client had now been formally charged.

French President Francois Hollande said Friday shortly after Abdeslam's arrest in Brussels that he wanted to see him transferred to France as quickly as possible.
