Oil falls on Iran talks progress, euro zone worry

NEW YORK (Reuters) - Oil prices fell on Tuesday as signs of a deal between the U.N. nuclear watchdog and Iran on Tehran's nuclear program eased fears of oil supply disruptions, while the euro zone debt crisis continued to threaten economic growth.
International Atomic Energy Agency (IAEA) Director General Yukiya Amano said he expected to sign a deal with Iran soon to boost cooperation with the investigation into Tehran's nuclear activity, although differences remained.

A stronger U.S. currency can pressure dollar-denominated commodities like oil by making them more expensive to consumers using other currencies.
