SINGAPORE, May 5 (Reuters) - Brent crude oil futures slipped towards $66 a barrel on Tuesday, falling from a 2015 high, as Saudi Arabia considered halting bombing in Yemen to allow the delivery of aid, which eased concerns about oil supply from the Middle East.
A stronger U.S. dollar also weighed on the dollar-denominated commodity, while investors waited for data on U.S. commercial crude oil inventories later this week for more direction.
Brent crude oil futures slipped by 8 cents to $66.37 a barrel by 0215 GMT, after touching a 2015 high of $67.10 on Monday.
U.S. crude oil futures fell by 8 cents to $58.85 a barrel.
"The stronger U.S. dollar and also news out of Saudi Arabia that they are halting the bombings in Yemen are two push-pull factors affecting the oil prices at the moment," said Ben Le Brun, a market analyst at OptionsXpress in Sydney.
The Saudi foreign minister said on Monday the Saudi-led Arab alliance conducting air strikes against Houthi fighters in Yemen was considering calling a truce in specific areas to allow humanitarian supplies to reach the country.
Investors are also waiting for inventory data out of the United States later this week, Le Brun said. "Obviously if we see a further tightening in supplies in the U.S., then that might be a catalyst to drive prices higher."
A Reuters poll on Monday suggested commercial crude stockpiles had risen nearly 2 million barrels last week, building for a record 17th straight week.
Industry group the American Petroleum Institute will issue its own expectations for last week's stockpiles on Tuesday, before official data from the government's Energy Information Administration on Wednesday.
Investors are also waiting for the U.S. nonfarm payrolls report for April later in the week for clues on when the Federal Reserve may raise interest rates.
Still, oil price losses were limited by concern about supply out of Libya, with protesters shutting down the eastern Libyan port of Zueitina, one of the few Libyan ports still exporting oil.
Libyan oil production has fallen to less than 500,000 barrels a day, a third of what it used to pump in 2010.
