US President Donald Trump has shared a video of a massive explosion in Iran, which, according to media reports, took place in the city of Isfahan in the early hours of Tuesday. The footage shows a series of blasts, followed by massive fires lighting up the night sky in orange hues. Trump did not provide any context to the video, but media reports claim it's of the US and Israeli joint strikes on a major ammunition depot in Isfahan, an Iranian city with a population of 2.3 million and home to the Badr military airbase. NDTV could not independently confirm the authenticity of the clip. According to a US official cited by The Wall Street Journal, US forces hit the ammunition depot in Isfahan with 2,000-pound (approx. 907-kilogram) bunker buster bombs. "A high volume of bunker busters, or penetrator munitions, was used for the strike," the official said.
