LONDON: Oil prices rose about one per cent on Wednesday from the previous session's two-month lows, after Iran's security chief said Teheran would not allow even a single particle of enriched nuclear material to leave the country.

Washington has said nuclear matters must be part of any initial negotiations with Teheran aimed at ending the US-Israeli war on Iran.

Brent futures were up US$1.26, or 1.4 per cent, to US$92.75 a barrel at 1158 GMT. US West Texas Intermediate crude gained 57 cents, or 0.7 per cent, to US$86.61.

In the previous session, oil prices initially fell by more than US$3 a barrel after US officials played down the need for further military strikes against Iran. Prices later pared some losses after an Iranian security official said no talks were taking place between the two sides.
