Toronto police are investigating after a firearm was discharged at the United States consulate in the Canadian city on Tuesday morning.

Officers responded to reports of shots fired at 5:29 a.m. local time at the American diplomatic facility. Police confirmed they found evidence of a discharged firearm at the scene but reported no injuries from the incident.

The Toronto Police Service announced the investigation through a social media post, providing few additional details about the circumstances surrounding the discharge or potential suspects.

The incident comes amid heightened security concerns at US diplomatic facilities internationally. On Sunday, Norwegian police investigated an explosion that occurred outside the US embassy in Oslo, though no connection between the two incidents has been established.

US consulates serve as diplomatic outposts that provide services to American citizens abroad and handle visa applications for foreign nationals seeking to travel to the United States. The Toronto consulate is one of several US diplomatic facilities operating in major Canadian cities.
