LONDON (Reuters) - Oil rose to over $91 a barrel on Tuesday after Turkish troops crossed over into Kurdish territory in northern Iraq.
Three hundred Turkish troops crossed the border overnight to combat Kurdish militants sheltering in the semi-autonomous region and blamed for attacks on Turkish territory.
U.S. light crude for January delivery, which expires later on Tuesday, rose 81 cents to $91.44 a barrel by 10:21 a.m., recouping some of the losses after falling for three straight sessions.
London Brent crude was up 55 cents at $91.84.
Analysts said rising geopolitical concerns centred on the oil-producing Mideast had put fundamental factors such as tight fuel stocks during an intensifying winter season into sharper focus.
