LONDON, March 4 (Reuters) - Crude oil rose on Friday, with Brent staying above $115 a barrel, as Libyan security forces began a violent crackdown on protesters in Tripoli and clashed with rebels near the major oil terminal of Ras Lanuf.
By 1409 GMT, Brent crude futures for April delivery <LCOc1> were up 71 cents to $115.50 a barrel, after earlier touching $116.30. U.S. crude futures for April <CLc1> rose $1.08 cents to $102.99 a barrel. The intraday high was $103.57.
Investors and traders have been nervously tracking the civil unrest in North Africa and the Middle East for any sign that Saudi Arabia, OPEC's leading oil producer, would be affected.
On Thursday Saudi Shi'ites staged protests in two towns in its oil-producing Eastern Province, demanding the release of prisoners they say are being held without trial. [
]In Libya, security forces fired shots and used tear gas to disperse a protest against Muammar Gaddafi's regime in the capital Tripoli. Demonstrators began the protest in the city's eastern district after Friday prayers. [
]Meanwhile, rebels advanced on the major oil terminal of Ras Lanuf, clashing with forces loyal to Gaddafi. [
]The head of Libya's rebel National Libyan Council vowed "Victory or death", in a short speech in the town of Al Bayda in the rebel-held east of the country. [
]A rebel spokesman told Al Jazeera television that rebel forces will attack Tripoli once a "no-fly" zone is enforced by international powers. [
] He added that rebel forces had repelled an attempt by Gaddafi forces to seize control of Brega airport in the rebel-held east.Barclays Capital analysts said in a note the chances of a swift resolution in areas of tension had reduced considerably.
"Libyan oil is likely to be lost to the market for an extended period, tying up considerable amounts of replacement oil in much longer supply chains, and events in Nigeria, Iraq, Iran and Bahrain are likely to provide a continuing backdrop of headline risks," they said.
SAUDI ARABIA
While the market focuses on the Shi-ite protests in Saudi Arabia, Christophe Barret, global oil analyst at Credit Agricole Corporate and Investment Bank, said he thought the risks were exaggerated.
"Saudi Arabia is the main risk in the region. It has all the spare capacity, and if there is unrest and production disruption, then it means an explosion in oil prices. But I think the risk is an exaggeration," he said.
He argued there were always problems between the Shi-ites and the Sunnis. "I don't think it will go like Libya, but the Eastern Province is a significant oil-producing province of Saudi Arabia, so that is why everyone is looking at it."
Unrest continues in other parts of the region. Iraqi security forces used water cannon and batons to disperse protesters in the southern oil hub of Basra as thousands of Iraqis rallied around the nation against corrupt officials and poor basic services. [
]Shi'ite Muslim rebels in northern Yemen said the military had fired rockets at their anti-government protests. [
] And in Bahrain several people were reported hurt in fighting between Sunni and majority Shi'ite Muslims. [ ]"Tension in the Middle East is like a runaway train," said Michael Hewson, an analyst at CMC Markets. "Once it starts it's very difficult to stop. And if there is a danger that it impacts the supply chain, people will understandably get nervous."
Libya's oil output has fallen to 700,000-750,000 barrels per day (bpd) from normal levels of 1.6 million bpd as most foreign oil workers have taken flight, according to Shokri Ghanem, the head of Libya's state-owned oil company. [

"As long as people keep reading about fighting in Libya and protests in the Middle East, it keeps the geopolitical risk premium in the forefront," he said. (Additional reporting by Florence Tan and Robert Gibbons, editing by Jane Baird)
