Low-level experts from Iran and several major powers are meeting in Turkey today to discuss how to end the stalemate over Iran's nuclear program . . . the meeting is being held after last month’s high level meeting in Moscow failed and could only agree to a low-level follow-up . . . Iran is refusing to discuss cutting back its uranium enrichment program unless all Western sanctions against it are first dropped, a demand the West finds unacceptable . . .  tensions with Iran are increasing due to an EU oil embargo that came into force on July 1, Iranian threats to close the strait of Hormuz, and an increased U.S. naval presence in the Persian Gulf . . . Iran announced today it had successfully test fired several short and long-range missiles, including a Shahab-3 with a range of 800 miles . . . tensions are too high for any meaningful agreement at today’s nuclear talks with Iran or to schedule another high-level meeting . . . the meeting will probably agree to hold another low-level meeting in about a month to maintain a dialogue with Iran in hope of making progress toward a diplomatic solution at a later date.
