The Pentagon, headquarters of the U.S. Department of Defense in Washington, D.C., has launched an investigation into leaks of classified information. This move comes after top-secret documents were apparently accessed or disseminated without authorization. It's a stark reminder of the importance of safeguarding sensitive information, especially in a world where cyber threats and espionage continuously evolve. The investigation seeks to determine the extent of the breach and tighten security measures to prevent future incidents.
