Iran army declines comment on MP's remarks to close the Strait of Hormuz
The legislator, Parviz Sarvari, told the student news agency ISNA: "Soon we will hold a military maneuver on how to close the Strait of Hormuz. If the world wants to make the region insecure, we will make the world insecure."

Located between Oman and Iran, the Strait of Hormuz connects the Persian Gulf with the Gulf of Oman and the Arabian Sea. Hormuz is the world's most important oil chokepoint due to its daily oil flow of 15.5 million barrels in 2009, down from a peak of 17 million bbl/d in 2008. Flows through the Strait in 2009 are roughly 33 percent of all seaborne traded oil (40 percent in 2008), or 17 percent of oil traded worldwide.
