The conflict escalated after Iran struck infrastructure around the Gulf in retaliation for a week of intensifying US attacks, which Iran said had hit an airport, a railway station, and bridges. Tehran also launched fresh strikes in Jordan, where the US military's Central Command said two service members were killed Friday as they 'defended against Iranian ballistic missile and drone attacks.'

Iran's Supreme Leader Mojtaba Khamenei said the ongoing attacks on his country 'once again demonstrated to everyone the worthlessness of the American president's signature'. He warned that the US should know that the 'dear Iranian nation and the axis of resistance have unforgettable lessons to offer it.'

Iran's energy ministry has urged citizens to reduce electricity use and switch off air conditioners in peak hours after the power grid was hit. The health ministry said Friday that 50 people had been killed since the renewed fighting broke out and more than 500 injured. Kuwait accused Tehran of targeting civilian sites and vital infrastructure, with residents voicing fears that the renewed hostilities might drag on.

In a statement carried by state TV, Iranian supreme leader Mojtaba Khamenei said: 'Now that the American enemy seeks to incite war and bear its most serious consequences, it should know that the dear Iranian nation and the axis of resistance have unforgettable lessons to offer it.'

Major General Mohsen Rezaei, a senior military adviser to Khamenei, warned that Tehran would resume 'full-scale offensive operations' if US strikes continued in the coming days. 'Iran will no longer limit itself to retaliatory, like-for-like responses,' Mohsen said, according to state media.
