Oil extends gains on little sign of progress in US-Iran talks

SINGAPORE, Sept 24 (Reuters) - Oil prices extended gains on Thursday after climbing 4% in the previous session as diplomatic talks between the United States and Iran showed no concrete sign of progress.

Brent crude futures LCOc1 rose 43 cents, or 0.4%, to $103.51 a barrel at 0630 GMT, while West Texas Intermediate futures CLc1 climbed 35 cents, or 0.4%, to $92.51 a barrel.

The benchmarks fell in Asian morning trade on Thursday but later rebounded as investors struggled to find a clear direction amid the geopolitical deadlock.

Iran and the US remain divided over how to bring an end to their war, but diplomacy must continue, a senior Iranian official told Reuters on Wednesday, after Iran's president told the UN General Assembly that Tehran would never surrender to US pressure.

The official said Tehran was reviewing Washington's response to its peace proposals, which prioritise lifting a US naval blockade on Iranian ports and reopening the Strait of Hormuz.
