Iran said Tuesday its armed forces had conducted new ballistic missile tests to demonstrate "deterrent power" and the country's "all-out readiness to confront threats" against its territorial integrity.

The announcement was carried by the official IRNA news agency, describing a military drill in which "ballistic missiles were fired from silos" in different parts of the country.

Washington imposed new sanctions over Iran's missile programme in January almost immediately after separate sanctions related to Iran's nuclear programme had been lifted.
