Moazzam Begg was incarcerated for three years
Former Guantanamo Bay detainee Moazzam Begg and a 44-year-old woman have been charged with terror offences related to Syria, West Midlands Police have said.
The force said Mr Begg, 45, of Hall Green, Birmingham, is accused of providing terrorist training and funding terrorism overseas.
The woman, Gerrie Tahari, of Sparkbrook, Birmingham, is charged with facilitating terrorism overseas.
They will appear at Westminster Magistrates Court on Saturday.
Both were arrested on Tuesday. Two other men arrested the same day remain in police custody.
They are a 36-year-old man from Shirley, Solihull, and a 20-year-old man from Sparkhill, Birmingham, who were held on suspicion of facilitating terrorism overseas.
Mr Begg was held in the US-run military prison at Guantanamo Bay in Cuba for nearly three years.
He is a British citizen who moved to Afghanistan with his family in 2001, before moving again to Pakistan in 2002 when the Afghanistan War started.
He was detained in Islamabad in January 2002 and taken to Bagram internment centre in Afghanistan for about a year before being transferred to the Guantanamo camp.
He was released in January 2005 along with three other British citizens and returned to the UK.
Mr Begg, who is now a director of campaign group Cage which helps the families of people who have been detained, had never previously been charged with an offence.
