US President Donald Trump, asked on Monday if he thinks Iran was responsible for the flydubai plane incident, said he personally does.
Earlier on Monday, US Vice President JD Vance said he has not seen anything conclusive yet on an Iranian role in the flydubai incident.
Vance spoke to reporters before leaving on a flight to Alaska.
He also told reporters that he will campaign in Michigan in about a week and a half, a competitive state in the November midterm election.
In the same conversation at the White House, Trump told reporters that the United States will help Russia after a laboratory worker died at a plague research institute in Siberia.
