Israel and Iran have begun a new round of attacks, as the conflict between the two heavily armed rivals enters its fourth day.

TEL AVIV, Israel (AP) — Iran fired a new wave of missile attacks on Israel early Monday, killing at least five people, while Israel claimed in the fourth day of the conflict that it had now achieved “aerial superiority” over Tehran and could fly over the Iranian capital without facing major threats.

The targeting of leaders and sensitive sites relied on activating intelligence teams, pre-positioned weapons and other capabilities that had long lain dormant.
