Iran accused the United States of being complicit in Israel's attacks on the Islamic Republic, which Washington denied, telling Tehran at the United Nations Security Council that it would "be wise" to negotiate over its nuclear programme.

Further strikes from Iran on Israel have left many people killed and dozens injured as the fiery war between the two nations continues.

Israel unleashed airstrikes across Iran for a third day Sunday and threatened even greater force as some Iranian missiles evaded Israeli air defenses to strike buildings in the heart of the country.
