Ayatollah Ali Khamenei, who assembled theocratic power in Iran over the decades as its supreme leader and sought to turn it into a regional powerhouse, bringing it into confrontation with Israel and the United States over its nuclear program while crushing democracy protesters at home, has died. He was 86. Iranian state media reported the death early Sunday, after a major attack launched by Israel and the United States. U.S. President Donald Trump said hours earlier that Khamenei had been killed in the joint operation. Khamenei dramatically remolded the Islamic Republic since he took the reins after the death of Ayatollah Ruhollah Khomeini in 1989.
