A wave of powerful overnight strikes has rocked Isfahan, Iran, triggering massive explosions and a towering column of fire that lit up the skyline and raised fears of further escalation in the region.

The joint US-Israeli attacks hit multiple locations across the city, sparking widespread fires and sustained blasts. Witnesses described intense detonations echoing across neighborhoods, with flames rising high into the night sky, The Caspian Post reports via foreign media.

Home to around 2.3 million people, Isfahan is considered a key strategic hub, hosting critical infrastructure including the Badr military airbase. The scale of the strikes appear significantly larger than previous incidents, with fires reportedly spreading across areas linked to military facilities.

Videos and images circulating online show continuous explosions followed by a massive plume of fire. Some of the footage was also reshared by US President Donald Trump.

The latest strikes come despite earlier signals that Tehran and Washington were exploring the possibility of a ceasefire. Instead, the escalation suggests a widening military campaign targeting defense and logistical assets inside Iran.

Isfahan has faced repeated attacks since early March, though earlier incidents were more limited. This latest wave stands out for its intensity, duration, and visible destruction.

With attacks growing in scale and frequency, concerns are mounting over a broader regional spillover and potential disruptions to global energy markets. For now, there are no clear signs of de-escalation, as tensions continue to rise.
