TEHRAN, Iran - The United States on Dec. 28 warned Iran that any move to block shipping in the Strait of Hormuz, the world's most important oil transit channel, will not be tolerated.

The chief of Iran's navy, Adm. Habibollah Sayari, said in an interview with Iran's Press TV that "shutting the strait for Iran's armed forces is really easy - or as we say [in Iran] easier than drinking a glass of water."
"But today, we don't need [to shut] the strait because we have the Sea of Oman under control, and can control the transit," he said.
Washington responded with a strong warning against any attempt to disrupt shipping at the entrance to the Gulf, through which more than a third of the world's tanker-borne oil passes.
"Interference with the transit ... of vessels through the Strait of Hormuz will not be tolerated," Pentagon press secretary George Little said.
The strait is a strategic choke point linking the Gulf's petroleum-exporting states of Bahrain, Iran, Kuwait, Qatar, Saudi Arabia and the United Arab Emirates to the Indian Ocean.
The United States maintains a naval presence in the Gulf in large part to ensure that passage for oil remains free.
Sayari was speaking a day after Vice President Mohammad Reza Rahimi threatened to close the strait if the West imposed more sanctions on Iran, and as its navy held war games in international waters to the east of the channel.
World prices briefly climbed after Rahimi warned Dec. 27 that "not a drop of oil will pass through the Strait of Hormuz" if the West broadened sanctions against Iran over its nuclear program.
"The enemies will only drop their plots when we put them back in their place," the official news agency IRNA quoted Rahimi as saying.
Sayari asserted that the Strait of Hormuz "is completely under the control of the Islamic Republic of Iran."
He said Iran's navy was constituted with the aim of being able to close the strait if necessary.
"The Iranians conduct exercises on a fairly routine basis in this area. That's something that we know about," Little said in Washington. "That being said, any effort to raise the temperature on tensions surrounding the Strait of Hormuz is unhelpful," he said, adding that there was no sign of Iran taking provocative steps near the channel.
"I'm unaware of any aggressive hostile action directed toward U.S. vessels in the Persian Gulf or the Strait of Hormuz," or against other ships, Little said.
As Iran staged its military maneuvers, the American aircraft carrier John C. Stennis, and the guided-missile cruiser Mobile Bay moved through the Strait of Hormuz.
Little said this was "a pre-planned, routine transit" on the way to the Arabian Sea to provide air power for the war in Afghanistan.
France on Dec. 28 called on Tehran to respect international law and allow unhindered passage of all vessels through the strait.
Sayari, meanwhile, said the Islamic republic's naval maneuvers were designed to show Gulf neighbors the power of its military over the zone.
Iranian ships and aircraft dropped mines in the sea Dec. 27 as part of the drill, and on Dec. 28 drones flew out over the Indian Ocean, according to an Iranian Navy spokesman, Adm. Mahmoud Mousavi.
Iran has said several times it is ready to target the strait if it is attacked or economically strangled by Western sanctions over its nuclear program.
An Iranian lawmaker's comments last week that the exercises would block the Strait of Hormuz briefly sent oil prices soaring before that was denied by the government.
Tehran in September rejected a Washington call for a military hotline between the capitals to defuse any "miscalculations" that could occur between their navies in Gulf waters.
U.S. State Department deputy spokesman Mark Toner dismissed Rahimi's threat as another attempt "to distract attention from the real issue, which is their continued non-compliance with their international nuclear obligations."
The United States and other Western countries accuse Iran of using its uranium enrichment program to build nuclear weapons. Tehran denies the charge.
Extra U.S. and European sanctions aimed at Iran's oil and financial sectors are being considered. A European Union spokesman said on Dec. 28 the bloc was pressing ahead with those plans regardless of Tehran's threat.
