LONDON, Feb 17 (Reuters) - North Sea Brent crude oil extended gains towards $104 a barrel on Thursday, near a two-and-a-half-year high as Israel-Iran tension and unrest in the Middle East stoked fears of a disruption of oil flows.
Bahrain police stormed a square in Manama, killing at least three people as protests in the Middle East and North Africa, inspired by revolts in Tunisia and Egypt, gathered pace. [
] [ ]Clashes were reported in tightly controlled oil producer Libya, sandwiched between Egypt and Tunisia, and people there prepared to take to the streets for a "day of rage" after new protests erupted in Yemen, Iran and Iraq.
The dollar hit a one-week low against a basket of currencies on worries over rising Middle East tension. [
]"All in all, the pace of change sweeping the region is truly mind-boggling, and we find it unlikely oil prices will 'settle' any time soon as long as this kind of upheaval continues to spread," said Edward Meir, senior commodity analyst at brokers MF Global.
Brent crude for April delivery <LCOc1> rose 10 cents to $103.88 by 0949 GMT, after settling $2.14 higher at $103.78, its highest close since September 2008, and off an earlier intraday high of $104.52.
U.S. crude for March delivery <CLc1> fell 39 cents to $84.60 a barrel, after settling up 67 cents at $84.99 on Wednesday, snapping three straight days of losses.
U.S. crude was depressed by industry data showing U.S. crude stocks rose last week, albeit less than expected.
The spread between Brent and U.S. crude <CL-LCO1=R> held above $16 per barrel after hitting a record of $16.31 a barrel on Wednesday.

SUEZ
Tensions between Israel and Iran continued to rattle markets already spooked by anti-government protests in the Middle East.
Suez Canal officials said on Thursday plans by two Iranian naval ships to cross the waterway had been cancelled. [
]Israeli Foreign Minister Avigdor Lieberman said on Wednesday the ships were expected to pass through the Suez Canal overnight en route to Syria in a move he described as a "provocation."
Also helping widen the Brent-WTI premium was the latest rise in inventory levels at the Cushing, Oklahoma, delivery point for the New York Mercantile Exchange oil futures contract.
Crude stored at the hub rose 250,000 barrels last week to 37.7 million barrels, just below the 38.3 million barrel record level hit in the week to Jan. 28, the Energy Information Administration's weekly data showed. [
]In total, U.S. crude stocks rose 860,000 barrels to 345.9 million barrels, its fifth straight weekly gain, but the increase was less than the forecast 2.2 million-barrel rise.
A raft of U.S. economic reports, due later on Thursday, will shed light on the pace of growth and price pressures in the world's biggest oil consumer.
The U.S. Labor Department will unveil first-time claims for jobless benefits for the week ended Feb. 12 at 1330 GMT. Economists forecast a total of 400,000 new filings against 383,000 in the prior week.
January consumer price data will also be released at 1330 GMT. Economists expect a 0.3 percent increase compared with a 0.4 percent rise in December. (Additional reporting by Jennifer Tan; editing by James Jukwey)
