Tehran: Iran on Sunday accused the United States of "adventure-seeking" policies in the Middle East and
said Washington owed the region an apology over a naval incident in the Gulf last week.

Iran and the United States have released videos and audio giving conflicting versions of the incident in which Washington says Iranian boats threatened US  ships in the Strait of Hormuz.

Foreign Ministry spokesman Mohammad Ali Hosseini said Iran had acted with restraint over the incident but the United States sought to use it to paint the Islamic state in a negative light.

"We exercised restraint and we very calmly announced that this was a routine procedure but they tried to create a certain amount of commotion here," Hosseini told a news conference.

"What we witnessed shows that some circles inside the United States are still pursuing its adventure-seeking policies," Hosseini said.

"We advise them not to pursue such policies of fooling the people in the region and now I think they have to apologise to the people of the region and also to the American nation," he said.

Bush visited the US Navy's Fifth Fleet in Bahrain on Sunday and the fleet's commander made it clear his forces took the incident in the Gulf "deadly seriously", White House spokeswoman Dana Perino said.
