(CNN) Intelligence officials have declassified a photograph of an Iranian missile on a small boat in the Persian Gulf in their efforts to help show the increasing threat from Iran as divisions grow within the Trump administration about what the intelligence means, the New York Times reported.

Meanwhile, President Donald Trump has become frustrated with some of his top advisers over his administration's approach to Iran, according to the Washington Post

CNN first reported last week that US intelligence showed Iran moving short-range ballistic missiles aboard boats in the Persian Gulf. The intelligence was one of the critical reasons the US decided to move an aircraft carrier strike group and B-52 bombers into the region, several US officials with direct knowledge of the situation told CNN.

The photographs of the Iranian missiles are the intelligence that caused the White House to increase its warnings about a threat from Iran, the Times reported Wednesday.

Two US officials told the newspaper that the declassified photograph alone isn't convincing enough validation of a threat from Iran. The declassified photograph has not been released by the Department of Defense.
