Tensions High, US Warns Iran Not to Block Shipping

Tensions rising by the day, the Obama administration said Friday it is warning Iran through public and private channels against any action that threatens the flow of oil from the Persian Gulf. The Navy revealed that two U.S. ships in and near the Gulf were harassed by Iranian speedboats last week.

Spokesmen were vague on what the United States would do about Iran's threat to block the strategic Strait of Hormuz, but military officials have been clear that the U.S. is readying for a possible naval clash.

That prospect is the latest flashpoint with Iran, and one of the most serious. Although it currently overshadows the threat of war over Iran's disputed nuclear program, perhaps beginning with an Israeli military strike on Iran's nuclear structure, both simmering crises raise the possibility of a shooting war this year.
