For decades, Israel and Iran have fought a shadow war across the Middle East, trading attacks by land, sea, air and in cyberspace. A recent round of strikes -- mainly an aerial barrage by Iran against Israel last weekend -- has brought the conflict more clearly into the open and raised fears of a broader war. A retaliatory Israeli strike on an Iranian air base on Friday, however, appeared limited in scope, and analysts said it suggested an effort to pull back from the dangerous cycle and potentially move the war back into the shadows. August 2019: An Israeli airstrike killed two Iranian-trained militants in Syria, a drone set off a blast near a Hezbollah office in Lebanon and an airstrike in Qaim, Iraq, killed a commander of an Iran-backed Iraqi militia. Israel accused Iran at the time of trying to establish an overland arms-supply line through Iraq and northern Syria to Lebanon, and analysts said the strikes were aimed at stopping Iran and signaling to its proxies that Israel would not tolerate a fleet of smart missiles on its borders.

A man who US officials called the leader of the Islamic State militant group in Syria was killed Tuesday in a drone strike while riding a motorcycle in the northern part of the country, the Pentagon and local organizations said. Maher al-Agal was killed near Jindires in northern Syria, and one of his top aides was seriously injured in the attack, Pentagon Central Command spokesman Lieutenant Colonel Dave Eastburn told AFP. The volunteer Syrian Civil Defense Force, known as the "White Helmets," said the attack targeted the two while they were on a motorcycle outside Aleppo. President Joe Biden said the strike "takes a key terrorist off the field and significantly degrades the ability of ISIS to plan, resource, and conduct their operations in the region." The Syrian Observatory for Human Rights confirmed Agal's death and said he was the Islamic State governor for the Levant region.
