Israel seems to have stuck to small drones when it hit Iran — suggesting it wanted only a minor retaliation

• An Israeli strike hit Isfahan in Iran, multiple outlets reported, citing unnamed senior US officials.
• It came after Iran fired drones and missiles at Israel in its first-ever direct attack.
• Analysts say the nature of Israel's response suggests it wants to limit the conflict.

The relatively restrained nature of the apparent Israeli attack on Iran suggests both sides are seeking to step back from the brink of a regional war, analysts say.
