A gunman was shot and killed by Secret Service agents after opening fire near a White House security checkpoint, authorities confirmed. A bystander was also struck by gunfire during the incident and sustained injuries. The shooting occurred in the vicinity of the perimeter surrounding the White House complex in Washington, D.C.

The Secret Service responded to the threat and neutralized the suspect. Officials confirmed the White House grounds themselves were not breached. Law enforcement secured the scene and launched an investigation into the circumstances surrounding the attack.

The injured bystander was transported for medical treatment. Their condition was not immediately specified in initial reports. Witnesses in the area reported hearing shots fired before law enforcement moved to lock down the surrounding streets.

Authorities have not publicly identified the suspect or released a confirmed motive. Investigators were working to determine whether the attack was planned or spontaneous, and whether the White House itself was the intended target. The area around Lafayette Square and nearby streets was temporarily closed to the public as the investigation proceeded.

The incident drew widespread coverage and prompted renewed discussion about security protocols around one of the most heavily protected buildings in the world. The Secret Service has faced heightened scrutiny over perimeter security in recent years following a series of intrusion attempts near the executive mansion.
