WASHINGTON (AP) — Israel demonstrated its military dominance over adversary Iran in its apparent precision strikes that hit near military and nuclear targets deep in the heart of the country, meeting little significant challenge from Iran’s defenses and providing the world with new insights into both militaries’ capabilities.

The international community, Israel and Iran all signaled hopes that Friday’s airstrikes would end what has been a dangerous 19-day run of strikes and counterstrikes, a highly public test between two deep rivals that had previously stopped short of most direct confrontation.

The move into open fighting began April 1 with the suspected Israeli killing of Iranian generals at an Iranian diplomatic compound in Syria. That prompted Iran’s retaliatory barrage last weekend of more than 300 missiles and drones that the U.S., Israel and regional and international partners helped bat down without significant damage in Israel. And then came Friday’s apparent Israeli strike.
