US President Donald Trump posted footage claiming responsibility for the destruction of the B1 (Azimiyeh) Bridge in Karaj, a major infrastructure project west of Tehran, following US-led airstrikes.

Donald Trump has slammed Australia as he addressed the US from the White House where he gave an update on the Iran war, and revealed how the historic rescue of a US airman unfolded.

Trump on Monday threatened Iran with a wave of new attacks on power plants and bridges if it did not reopen the blockaded Strait of Hormuz, in an expletive-laden social media post.
