Nine U.S. warships in Gulf for show of force

By Mohammed Abbas

ABOARD USS JOHN C. STENNIS (Reuters) - The largest daytime assembly of U.S. warships in the Gulf since the 2003 Iraq war prepared on Wednesday to hold drills off Iran's coast in a major U.S. show of force that unnerved oil markets.

U.S. Navy officials said Iran was not notified of plans to sail nine ships, including two aircraft carriers, through the Straits of Hormuz, a narrow channel in international waters off Iran's coast and a major artery for global oil shipments.

The maneuver raises pressure on the Islamic Republic, coinciding with a report by the U.N. atomic watchdog on Iran's nuclear program, which could lead to tougher sanctions.

Oil climbed towards $70 as the U.S. ships sailed into the straits, through which 40 percent of globally traded oil passes.

Rear Admiral Kevin Quinn, who is leading the group, said the ships would conduct exercises as part of a long-planned effort to reassure regional allies of U.S. commitment to Gulf security.

"There's always the threat of any state or non-state actor that might decide to close one of the international straits, and the biggest one is the Straits of Hormuz," he told reporters on board the USS John C. Stennis aircraft carrier.

Tension with the United States over Tehran's nuclear ambitions has raised regional fears of a military confrontation.

Highlighting the dangers of accidental escalation, a Navy official said the USS Stennis had received nine enquiries from nearby countries, two from Oman and seven from Iran, including one from an Iranian vessel that sailed close by.
