Israel Defense Forces (IDF) said it identified missiles launched from Iran toward Israel on Sunday and was activating its defensive systems to intercept the threat.

The Iran missile attack on Israel followed strikes carried out by the IDF this weekend on Iran-backed Hezbollah militant targets in southern Beirut, Lebanon.

The alleged missile attack aimed at Israel came just hours after Iranian lawmaker Ebrahim Rezaei promised a "decisive and painful response" to Israel’s airstrikes on southern Beirut on Sunday.

Rezaei, spokesman for the Security and Foreign Policy Committee of Iran’s Parliament, issued a statement on social media, threatening, "This rabid dog must be disciplined and put in its place. Look at the sky of the occupied territories tonight."

IDF sent out a precautionary directive to mobile phones of residents in the area targeted by Iran, asking them to act responsibly and follow instructions to save lives.

Upon receiving an alert, the public is being instructed to enter a protected space and remain there until further notice.

In his appearance before Congress on Wednesday, Secretary of State Marco Rubio described the tempo of what he called "kinetic actions" between the U.S. and Iran in recent days, which he characterized as a U.S. response to Iranian provocations.

"That is some commercial ship that didn't pay a toll and starts to move. That ship comes under attack by a drone. We shoot down the drone. In some cases, not only do we shoot down the drone, but we hit the launcher of the drone, so they can't hit the ship a second time," Rubio said.

"The Iranians then respond by launching two missiles or three at some base in the region as their response. And that's what you've seen play out three of the last four nights with regards to this," he added.

Rubio also discussed the nuclear element of the ongoing negotiations with Iran, saying that any new nuclear agreement would invoke legislation that would put the pact before Congress.

In response to a question from Sen. Lindsey Graham, Rubio said the administration wants a deal that would allow the U.S. to punish Iran for its continued support for the Hezbollah militia in Lebanon, but stressed that the "primary threat here is the nuclear weapons ... they can never have a nuclear weapon."

Uranium enrichment monitoring, Rubio added, will be "critical for any deal to be successful."

Rubio also told senators that the ongoing talks with Tehran are being complicated as the Iranian government is "fractured." He estimated it takes some between seven and 10 Iranian negotiators to pass proposals.

Rubio said this week that it often takes "three to five days to get a response" from the Iranian leadership.
