Residents near Iran's Semnan missile test range reported a dramatic nighttime ballistic missile launch on September 18, with multiple eyewitnesses describing a sudden roar and bright trail across the desert sky, IntelliNews can confirm from monitoring footage.

Semnan is approximately 219 kilometres (136 miles) east of Tehran. The Islamic Republic has long used the province as a base of its different military operations. 

This latest signal signals Iran's ongoing confidence in its strategic missile forces following the recent 12-day war with Israel, which was forced to end by the US after intervention by President Donald Trump, following the now infamous cursing on the White House lawn. 

The missile's silhouette and launch characteristics, particularly its rapid, smokeless ascent, led sources with knowledge of previous tests to suggest it was a Sejjil-class system, Iran's most advanced domestically produced medium-range ballistic missile.

Multiple videos from around Semnan report at least three rockets being launched in the local area, causing panic among many who believe the country is in a state of active military operations. 

The Sejjil uses two-stage, solid-fuel propulsion, enabling quick launch preparations and improved survivability against pre-emptive strikes. Its reported range of up to 2,500 kilometres places much of the Middle East and southern Europe within reach.

Iranian authorities released no official statement, which aligns with Tehran's policy of opacity around sensitive military activities amid an increased security atmosphere in the country.

Social media footage from the vicinity showed a missile lifting off vertically before accelerating and being shot down by local anti-missile cannons as part of a test.
