NEW YORK, Dec 30 (Reuters) - Oil fell over 3 percent on Tuesday, as signs of the sickly world economy outweighed tension in the Middle East due to the Israeli-Hamas conflict.
The fall came with a raft of demand-destructive news, including signs that the U.S. holiday shopping season was the weakest since 1970 and consumer confidence in the world's largest energy user was at record lows in December.
U.S. crude <CLc1> was down $1.36 at $38.66 a barrel by 11.44 a.m. EST (1644 GMT), having earlier touched a session high of $40.39.
London Brent <LCOc1> fell $1.12 cents to $39.43.
"Concerns over the state of the global economy eclipses fears that the conflict between Israel and Hamas will inflame tensions in the Middle East," Addison Armstrong, analyst at Tradition Energy, wrote in a note.
Oil prices had jumped as much as 12 percent on Monday after Israel launched its fiercest air offensive in the Hamas-ruled Gaza strip in decades. [
