Iran's Revolutionary Guards said on Thursday they targeted a US airbase after what they described as an early morning US attack near Bandar Abbas airport, Tasnim news agency reported.

The US military launched new strikes in Iran targeting a military site that officials believed posed a threat to US forces and commercial maritime traffic in the strait, a US official told Reuters.
