US President Donald Trump said he personally believes Iran was responsible for the recently thwarted terrorist attack on a Flydubai airlines, even as investigators haven't announced any conclusion that the suspect is tied to Iran or another foreign entity.

Axar.az informs, citing USA Today, "I do. I personally do," Trump said when asked on Oct. 5 by a reporter whether he believes Iran was responsible for the foiled attack.

The United Arab Emirates is leading an international investigation into the Sept. 30 attack of Flydubai airlines pilot Smit Machchhar, who was stabbed by his co-pilot in an apparent effort to crash the plane carrying 170 passengers. The plane was flying from Dubai to Tel Aviv.

Trump did not cite any information to back his claim of Iranian involvement. Hours before Trump's remarks, Vice President JD Vance said U.S. intelligence officials had not verified Iran was involved.

"That's something that I defer to (CIA Director) John Ratcliffe and some of the intelligence folks on," Vance said. "I don't want to get ahead of any announcements there, but it's certainly something that we're looking at. But I wouldn't say I've seen anything conclusively just yet."
