According to US Central Command (CENTCOM), the strikes targeted Iranian military surveillance capabilities, communication systems and air defence sites."US Marine Corps, Air Force, and Navy assets fired precision munitions on Iranian targets that posed a threat to US forces and international commercial ships transiting regional waters," CENTCOM said.Reuters reported that Iranian news agencies recorded explosions in several cities across the country, including Sirik, Kargan, Bandar Abbas and Minab in the southern province of Hormozgan. Strikes were also reported in Varamin and Karaj near Tehran.The latest attacks came a day after the US launched another round of strikes against Iranian military infrastructure after Washington accused Tehran of downing a US Apache helicopter near the Strait of Hormuz.Following Wednesday's strikes, US President Donald Trump warned Iran in a social media post, saying: "Iran is all talk and no action, They’ve taken too long to negotiate a deal that would have been great for them, now they will have to pay the price!!!"
