DUBAI, United Arab Emirates (AP) — Israel launched a new wave of strikes on Iran and threatened on Friday that its attacks “will escalate and expand” after U.S. President Donald Trump claimed talks on ending the war were going well and gave Tehran more time to open the Strait of Hormuz, though there have been no signs of Iran backing down.

Air raid sirens sounded in Israel as the military said it was working to intercept Iranian missiles in what has been a daily occurrence. Israel’s Defense Minister Israel Katz said Iran “will pay heavy, increasing prices for this war crime.”

“Despite the warnings, the firing continues,” Katz said. “And therefore attacks in Iran will escalate and expand to additional targets and areas that assist the regime in building and operating weapons against Israeli citizens.”

Israel’s military said its attack on Friday targeted sites “in the heart of Tehran” used by Iran to produce ballistic missiles and other weapons. It also hit missile launchers and storage sites in western Iran.

Smoke rose over Beirut after a pre-dawn strike, and Lebanon’s Health Ministry later reported two people were killed.
