NEW YORK, March 17 (Reuters) - Oil prices rallied by more than 3 percent on Thursday as unrest in the Middle East and North Africa added more worries about supply disruptions even as investors weighed impact on demand of Japan's earthquake disaster.
Bahrain's ongoing crackdown on Shi'ite protesters after Saudi Arabia sent in troops has provoked a complaint from Iran lodged before the United Nations, sparking worries of a wider regional unrest that could stifle oil production. [
]At the same time, analysts said damage to Libya's oil infrastructures in the wake of a rebellion may require a long period of repairs before it can recover production currently down about two-thirds of its normal 1.6 million barrel per day output.
In Japan, the government mounted a desperate bid to avert a catastrophe at a crippled nuclear complex, on the sixth day after a disastrous earthquake and tsunami struck its northern region, severely affecting demand in the world's third largest oil consumer. [
]"Prices are up as focus remains on tensions in the Middle East, particularly with the Saudi intervention in Bahrain" said Stephen Schork, editor of the Schork Report, a daily commentator on the energy markets, in Villanova, Pennsylvania.
By 12:45 p.m. EDT (1645 GMT), Brent crude for May delivery <LCOc1> rose $3.47 to $114.07 a barrel, after hitting a session high of $114.20.
U.S. crude for April delivery <CLJ1> gained $2.91 to $100.89, having rallied earlier to $100.97.
Both contracts continued to rebound from three-week lows struck on Wednesday when pessimism about Japan's nuclear crisis somewhat edged out tensions in the Middle East.
U.S. crude's sharp rise was also aided by upbeat data on jobless benefit claims and factory activity in the Mid-Atlantic region. Data showing that inflation remained contained despite rising prices also helped boost investor mood. [
]MIDEAST TENSIONS UNABATED
State-owned Bahrain Petroleum Co (BAPCO) has partly shut down production due to staff shortages caused by political unrest in Bahrain, trade sources said. [
]Bahrain arrested seven opposition leaders, a day after its crackdown on protests among the Shi'ite Muslim majority drew rare U.S. criticism and raised fears of a regional conflict. [
]Libyan troops pushed forward towards the insurgent stronghold of Benghazi and launched air raids on its outskirts as Washington raised the possibility of air strikes to stop Muammar Gaddafi's forces. [
]In Yemen, security forces used live fire and tear gas on on anti-government protesters, wounding at least 84, activities said. [
]"The focus is back on continuing unrest in the Middle East and what will be a lot of disruption in Libya for a long time," said Christopher Bellew, an oil trader at Bache Commodities.
"The risk is more to the upside -- there was a lot of long liquidation on that sharp sell off at the beginning of the week, so we will work our way a bit higher probably." <^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^
