A senior US official said that "diplomacy is continuing" despite intermittent strikes in Iran, CNN reported Friday.
The night passed without military action by either the US or Iran, but tensions remained high across the Middle East following the escalation in recent days.
Friday marked the third day of the latest round of escalation. It began with an attack on tankers in the Strait of Hormuz, followed by US strikes in Iran and Iranian missile and drone attacks targeting US bases in the Gulf region.
Meanwhile, former Iranian supreme leader Ali Khamenei was laid to rest four months after he was assassinated. His funeral procession passed through several Shiite holy cities.
His son, Iranian Supreme Leader Mojtaba Khamenei, was not seen during the procession, although other senior officials from the ayatollah-led regime attended.
Israel warns US of new Iranian plot to assassinate Trump as tensions in region grow
Israel shared intelligence with the US about a new Iranian plot to assassinate US President Donald Trump, the Wall Street Journal reported.
The Israeli Embassy in Washington declined to comment. Iran's mission to the UN did not immediately respond to a request for comment.
According to the report, the White House referred the Wall Street Journal to remarks Trump made Wednesday while speaking to reporters in Ankara, Turkey, during the NATO summit. Trump alluded to threats against his life.
"They want to eliminate the leader of the US, me," he said. "I am on every list. I saw this morning, I am on every one of their lists. And so far, I suppose I have been a little lucky, but that may not last much longer."
