Iran is boasting that it has hypersonic missiles and says it already has begun firing the cutting-edge weapons at Israel.

Iran announced it had launched some 100 missiles and vowed further retaliation for sweeping attacks on its military and nuclear infrastructure.

Hundreds of missiles were sent toward Israel, officials said, and several appeared to strike despite the country’s air defense systems. Interceptors also generated explosions near the ground as they fired to shoot missiles out of the sky. Sirens sounded across the entire country.
