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.

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

Iran fired a new wave of missile attacks on Israel early Monday, triggering air raid sirens across the country as emergency services reported at least five killed and dozens more wounded in the fourth day of a conflict between the regional foes that showed no sign of slowing.
