An explosion occurred in Tehran on Friday during the annual Quds Day rally, according to reports from the Iranian capital. The incident took place as demonstrators gathered for the traditional day of solidarity with Palestinians.

Quds Day, established in 1979, is observed annually on the last Friday of Ramadan with rallies held in Iran and other locations worldwide. The day is marked by demonstrations expressing support for Palestinian causes and opposition to Israeli policies.

The explosion in Tehran happened amid the scheduled rally, though details about casualties or the cause of the blast were not immediately available. Iranian authorities have not released official statements regarding the incident.

Separately, Palestinian solidarity groups in North America had organized Quds Day events in various cities across the United States and Canada. These demonstrations were planned as part of the annual observance that typically draws participants in multiple countries.

The timing of the Tehran explosion during the significant religious and political observance adds to concerns about security during large public gatherings in the region. Quds Day rallies have historically been major events in Iran's political calendar, often drawing large crowds to express support for Palestinian causes.
