HERE IS THE LATEST NEWS FROM THE MIDDLE EAST :
An Iranian patrol on Thursday spotted the nuclear-armed and -powered submarine in the strategic Strait of Hormuz, which allows the passage of 90 percent of the oil produced by Persian Gulf states to Asia, the US and Western Europe.
There are currently 48 logistic and 18 combat US vessels in the Persian Gulf waters, among them the USS-Eisenhower aircraft carrier.
Experts say aside from the risk of ecologically disastrous accidents, the presence of a nuclear submarine in a narrow waterway also poses a threat of nuclear pollution.
In 2009, a US Navy Los Angeles-class nuclear-powered submarine collided with a San Antonio-class amphibious transport dock in the strait. The incident caused a spillage of nearly 25-thousand gallons of diesel fuel.
In 2007, a submerged US nuclear vessel collided with a huge Japanese crude tanker in the south of the strait.
The US is yet to comment on the report.
