Iran president warns of 'massive' response if Israel launches 'tiniest invasion'

Iran: Iran's president has warned that the "tiniest invasion" by Israel would bring a "massive and harsh" response, as the region braces for potential Israeli retaliation after Iran's attack over the weekend.

President Ebrahim Raisi spoke Wednesday at an annual army parade that was relocated to a barracks north of the capital, Tehran, from its usual venue on a highway in the city's southern outskirts.

Iranian authorities gave no explanation for its relocation, and state TV did not broadcast it live, as it has in previous years.

Iran launched hundreds of missiles and drones at Israel over the weekend in response to an apparent Israeli strike on Iran's embassy compound in Syria on April 1 that killed 12 people, including two Iranian generals. (AP)
