JERUSALEM (AP) — Satellite photos taken Monday suggest an apparent Israeli retaliatory strike targeting Iran’s central city of Isfahan hit a radar system for a Russian-made air defense battery, contradicting repeated denials by officials in Tehran of any damage in the assault.

The strike on an S-300 radar in what appears to have been a very limited strike by the Israelis would represent far more damage done than in the massive drone-and-missile attack Iran unleashed against Israel on April 13. That may be why Iranian officials up to Supreme Leader Ayatollah Ali Khamenei have been trying to dismiss discussing what the attack actually did on Iranian soil.

Analysts believe both Iran and Israel, regional archrivals locked in a shadow war for years, now are trying to dial back tensions following a series of escalatory attacks between them as the Israel-Hamas war in the Gaza Strip still rages and inflames the wider region. But a strike on the most advanced air defense system Iran possesses and uses to protect its nuclear sites sends a message, experts say.
