While Israel's modest attack against Iran and Tehran's decision to downplay it suggest a desire to avoid escalation, Iran's options for retaliation (including the use of proxies in the region to strike Israel or small attacks against Israel itself) mean that the risk of a broader conflict remains heightened. Israel launched an attack against an Iranian military air base in the city of Isfahan in the early hours of April 19, with some sources, including the Jerusalem Post, reporting that Israel used missiles fired from fighter jets over Iraq, while others, including local Iranian media, suggested that it was a quadcopter drone attack. Iranian air defenses were reportedly activated in the city, with Iranian officials claiming that their defenses shot down the drones before they succeeded in causing any damage.
