Amid Iran threat to close strait US military hosts widely attended international naval exercise
Warships from around the world were assembling in the Gulf on Sunday for what the US military described as the most widely attended international naval exercise ever held in the Middle East.
The exercise, which Washington says involves manoeuvres to improve mine detection and clearance, comes at a time of rising regional tensions over Iran's controversial nuclear programme.
Tehran has threatened to block the Strait of Hormuz, through which 40 percent of the world's sea-borne oil exports passes, and target US military bases in the region if it was attacked.
The US Naval Forces Central Command said that the International Mine Countermeasures Exercise 12 involved vessels and officials from 30 countries in six continents. It did not name the participating nations.
"This exercise is about mines and the international effort to clear them," said Vice Admiral John W Miller, Commander of the Central Command, in a statement on its website.
"Represented here are the best of our individual countries' efforts dedicated to securing the global maritime commons and I look forward to seeing how this exceptional team of professionals moves forward."
The West and Israel believe Iran is seeking an atomic weapon, while Tehran says its work is for peaceful purposes.
Israel, concerned international sanctions have not stopped Iran's programme, has been pushing Washington to spell out limits Tehran must not cross if it is to avoid military action - something US President Barack Obama has refused to do.
Israeli Prime Minister Benjamin Netanyahu warned on Sunday that Iran was just six to seven months away from the brink of being able to build a nuclear bomb, adding urgency to his demand that Obama set a "red line" for Tehran.
Obama has asked Netanyahu to hold off on any Israeli strike on Iran's nuclear sites to give sanctions and diplomacy time to work.
The official US Navy News Service said last month that Washington was cutting short home leave for the crew of one of its aircraft carriers and sending them back to the Middle East to counter any threat from Iran.
The Central Command said the Gulf exercise was starting on Sunday with a meeting for senior commanders when they would view the latest mine hunting and disposal inventions. In the second phase, sea manoeuvres would be held including mine detection and clearance operations.
The Bahrain-based Central Command is responsible for an area comprising some 2.5m sq miles stretching from the Gulf to parts of the Indian Ocean.
