A U.S. federal judge has ordered the social networking website Twitter to turn over documents linked to WikilLeaks to the United States government.
The documents include information associated with WikiLeaks founder Julian Assange and U.S. Army computer programmer Bradley Manning.
Assange is currently free on bail in connection with a sex case in Sweden.
Private Manning is accused of providing WikilLeaks with the confidential diplomatic cables. He is under arrest.
U.S. officials said Friday the State Department is warning hundreds of foreign diplomatic sources identified in classified cables released by WikiLeaks of potential threats to their safety.
The New York Times newspaper says the department has moved a small number of the foreign government officials, businesspeople and human rights activists to safer locations.
U.S. officials and human rights groups criticized the WikiLeaks website last year for releasing thousands of Afghan war documents without removing the names of Afghan citizens who had helped the U.S. military. The group later decided to strip the names of what it called "innocent parties" when publishing more secret documents.
