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

Iran is firing fewer missiles at Israel each day, suggesting Tehran’s capabilities are being limited by Israeli attacks, or it is conserving what it has left. Israel says one reason is that it has destroyed more than a third of Iran’s launchers.

Prime Minister Benjamin Netanyahu of Israel presented Iran’s sophisticated ballistic missiles as a critical threat to Israel’s survival.
