Iran retaliated against the United States and Israel for fresh strikes in Beirut on Sunday, further dampening hopes for a lasting peace as the Middle East war reached its 100th day.

Efforts to turn a ceasefire into a settlement have repeatedly stalled, while the war has rattled global markets and increased domestic pressure on US President Donald Trump ahead of midterm elections.

Tehran has repeatedly insisted any deal to permanently end the war must also halt the parallel conflict in Lebanon, where Israel is pursuing a campaign against the Iran-backed movement Hezbollah.

Israel said Sunday that Iran launched missiles at it in the first such bombardment since a fragile ceasefire took effect in April. The strikes came after an Israeli air raid on Beirut’s southern suburbs killed two people and injured 20 people.

Iran on Saturday accused the U.S. of violating the ceasefire as the U.S. military shot down six Iranian one-way attack drones that were headed toward the Strait of Hormuz.

Seven ballistic missiles fired at Kuwait and Bahrain early Saturday local time were largely intercepted as well. The U.S. retaliated by launching strikes on Iranian coastal surveillance radar sites in Goruk and on Qeshm Island.
