Lawmakers in the United States have renewed provisions of the Patriot Act, a domestic surveillance law.
A four-year extension was approved in the Senate on Friday and the bill was then sent to the House of Representatives, where it passed by a vote of 250-153.
The Patriot Act was brought in under President George W Bush in 2001 after the attacks on September 11, 2001.
The White House issued a brief statement that President Barack Obama had signed the extension into law from France.
The bill enables law-enforcement officials to conduct continued surveillance on suspects who switch phones, monitor ''lone-wolf'' suspects who are not linked to known terrorist groups and gain access to their business transactions.
