Iran is one of the main security challenges of Azerbaijan, new U.S. ambassador to Azerbaijan Richard Morningstar told reporters in Baku on Monday.
"During my meetings with the officials we always touched on and will touch on this issue," Morningstar said.
The ambassador said that Washington will continue to work closely with Azerbaijan on this issue.
Regarding a letter from Congressman Dana Rohrabacher addressed to Hillary Clinton, the ambassador noted that the United States respects the recognized borders of Iran.
"Ideas of Congressman Rohrabacher do not reflect the official position of the United States," Morningstar said.
Earlier, the U.S. State Department confirmed receipt of a letter from Congressman Dana Rohrabacher addressed to Secretary of State Hillary Clinton on the need to support the fight for the independence of Azerbaijan province from Iran and the possibility of unification with the Republic of Azerbaijan.
