US Intelligence agencies will only use bulk collection of data for fighting terrorism, protecting troops and allies, as well as combatting crime, President Obama announced today, as he announced plans to curb the National Security Agency's authority.
President Obama added that a review of intelligence gathering practices will not be completed overnight, but said he wants the American people to know the "work has begun".
The US government is also to extend "certain protections" for Americans to people overseas that would limit time in which personal information can be held and how it can be used, Mr Obama announced.
