NEW YORK, Jan 24 (Reuters) - Oil prices fell on Tuesday on revived concerns about the euro zone's debt problems and their potential to slow the global economy, but tensions between Iran and the West helped limit losses.

Europe's policymakers are struggling to come up with a plan to prevent a Greek default, which would harm the global economy and depress demand for energy.

Euro zone finance ministers on Monday rejected as insufficient an offer made by bondholders to help restructure Greece's debts, sending negotiators back to the drawing board and raising the threat of a default.

"Crude oil prices are lower on the back of softer equities and a weaker euro on fresh worries over Greek debt," Tim Evans, energy analyst at Citi Futures Perspective, said in a note.

Brent March crude fell 55 cents to settle at $110.03 a barrel after reaching $111.11. It fell to $109.70 intraday, above front-month Brent's 100-day moving average (MA) at $109.55 and with the 50-day MA at $109.36 and the 300-day MA at $109.28 awaiting below as tests of support.
