TEHRAN, Iran – Anti-aircraft batteries opened fire across parts of the Iranian capital on Thursday evening, April 23, 2026, sending a wave of anxiety through the city. However, Iranian state media quickly moved to calm the public, characterizing the incident as a scheduled test of the city’s defensive systems.
Fears of Attack Dismissed
Reports of explosions and the distinct “thud” of air defence fire first emerged from western and eastern Tehran around 8:40 p.m. local time. Witnesses also reported seeing MiG-29 fighter jets patrolling the skies at low altitudes.
The Mehr News Agency later clarified that the activity was a response to detected micro aerial vehicles (MAVs) used during a routine surveillance test. Military officials confirmed that the current ceasefire period is being used to recalibrate radar systems and install new hardware, making such activations a necessary part of the city’s readiness protocols.
Regional Stance and Denial
The incident occurred against a backdrop of extreme regional tension. Despite the sounds of combat, an Israeli military source stated firmly that Israel was not involved in any operations within Iran on Thursday.
This follows earlier statements from Israeli Defense Minister Israel Katz, who noted that while Israel remains prepared for future engagement, it is currently adhering to the diplomatic window established by international mediators.
A Tense Truce
The activation highlights how jumpy the region remains under the current U.S.-brokered ceasefire. While peace talks continue, the presence of a U.S. naval blockade on Iranian ports and the ongoing reorganization of military assets on both sides mean that any unexplained sound in the capital is met with immediate concern.
No damage or casualties were reported following the exercise, and life in the capital returned to normal by late evening.
