Tensions between Iran and the United States have escalated following President Trump's announcement that a US naval force is heading toward Iran. A senior Iranian official has warned that any attack on Iran will be considered an 'all-out war' and promised a strong response. The official emphasized that Iran's military is on high alert and prepared for any scenario, as the US increases its military presence in the region. This standoff comes after recent protests in Iran and warnings from Trump against further violence or nuclear activity by Tehran.
