The two powers have been exchanging barrages since Israel attacked Iran and killed many of the country’s top military leaders and scientists.

Israel and Iran have begun a new round of attacks, as the conflict between the two heavily armed rivals enters its fourth day.

Israeli Prime Minister Benjamin Netanyahu said Monday that Israeli strikes have set Iran’s nuclear program back a “very, very long time.” He added that Israel was not attempting to topple the Iranian government, but said he would not be surprised if that happened as a result of the strikes.

Iranian news media and residents of Tehran say the damage from the latest Israeli strikes appears to be significant, with several apartment buildings badly damaged. Residents say they are hearing ambulance sirens and fire trucks racing to the scenes and rescue workers are working to find casualties in the rubble.

As tensions escalate between Iran and Israel, the spotlight now turns to Pakistan’s controversial stance. Iranian Security Council member Mohsen Rezaei claimed that Pakistan may support Iran with nuclear weapons if Israel attempts a nuclear strike.

President Donald Trump vetoed Israel’s plan to kill Iran’s Supreme Leader Ayatollah Ali Khamenei, according to a U.S. official familiar with the matter.

Gold prices soared on Friday as investors flocked to safe-haven assets following Israeli airstrikes on Iran, re-igniting fears of a broader conflict in the Middle East.
