London - Oil prices advanced Monday on escalating violence in crude producer Libya following a coup attempt by a rogue general that has raised concerns about potential supply disruptions, analysts said.
The US benchmark, West Texas Intermediate (WTI) for delivery in June, rose 71 cents to $102.73 a barrel.
Brent North Sea crude for delivery in July climbed 41 cents to stand at $110.16 a barrel in London midday deals and compared with Friday's closing level.
Armed groups attacked Libya's interim parliament and an airbase in the east Sunday, adding to turmoil in the country where a colonel claiming to speak on behalf of the army declared that parliament had been suspended.
“The situation in Libya is having a firm impact on sentiment,” Michael McCarthy, chief market strategist at CMC Markets in Sydney, told AFP.
“There has been no impact on supply but it is a good reminder to investors of potential disruptions that exist not only in Ukraine but also in oil-producing countries like Libya,” he said.
Since the toppling of dictator Moamer Kadhafi in 2011, successive Libyan governments have struggled to impose order as heavily armed former rebel brigades carve out their own fiefdoms.
The violence in Libya, a member of the OPEC cartel, comes just weeks after the resumption of oil exports following a nine-month blockade of sea terminals by rebels.
Its exports are expected to quadruple to one million barrels per day by mid-June, as slashed output is restored.
McCarthy said oil prices also remain propped up by the Ukraine crisis, where rebels are attempting to break away from the former Soviet state and become a part of Russia.
Ukraine is a major conduit for Russian oil and gas exports to Western Europe, and analysts fear that an escalation of the crisis could hit supplies and send prices soaring.
