LONDON, Jan 8 (Reuters) - Oil fell on Thursday to below $42, after a 12 percent drop overnight, weighed by mixed U.S. jobless data and higher than expected crude stocks that hardened evidence of weakening demand.
U.S. crude for February delivery <CLc1> was down 95 cents at $41.68 a barrel by 1356 GMT, after sinking 12.3 percent overnight to $42.63, its biggest one-day percentage loss since Sept. 24, 2001.
London Brent crude <LCOc1> fell 31 cents to $45.55.
Earlier, crude traded up by $1.00, touching $43.63.
"This morning crude was trying to rally a bit, but more figures kept coming out from the U.S. and they were very bearish indeed," said Sucden trader Rob Montefusco.
The number of U.S. workers filing new claims for unemployment benefits fell unexpectedly by 24,000 last week, government data showed on Thursday, but the number of people remaining on jobless rolls rose to a 26-year high. [
]Initial claims for state unemployment insurance benefits fell to a seasonally adjusted 467,000 in the week ended Jan. 3 from a slightly downwardly revised 491,000 the prior week, the U.S. Labor Department said.
Analysts polled by Reuters had forecast 540,000 new claims versus a previously reported figure of 492,000.
Oil had taken a battering after U.S. Energy Information Administration (EIA) data on Wednesday showed crude stocks up 6.7 million barrels, more than seven times the 900,000-barrel increase analysts expected. [
]"Brent is done going under $40, but WTI is a different animal altogether...crude stocks in the Midwest are very high because Cushing is a landlocked base with pipes that only go in one direction," Christopher Bellew of Bache Financial said.
CUSHING STORAGE
Crude oil storage at the Cushing, Oklahoma storage hub rose 4.1 million barrels to 32.2 million barrels in the week to Jan. 2, according to Wednesday's EIA data, a new record that may test capacity, an official at the EIA said. [
]Prices had gained some support from violence in Gaza, widening natural gas supply disruptions due to a row between Russia and Ukraine, and mounting evidence of OPEC's compliance with production cuts.
Three rockets fired from Lebanon struck northern Israel on Thursday, slightly wounding two people and prompting the Jewish state to respond with artillery fire, officials said. [
]While the conflict does not directly threaten any oil supplies, Middle East unrest can bolster prices because countries in the region pump about a third of the world's oil.
Russia and Ukraine failed to resolve a gas row at a meeting in Moscow but will continue talks to end the dispute which has choked off supplies to Europe, a senior Ukrainian gas official said on Thursday. [
]The dispute has cut heating to hundreds of thousands of people across the Balkans and hit supplies as far west as France and Germany as Europe faces freezing temperatures.
Signs that members of the Organization of the Petroleum Exporting Countries (OPEC) are implementing the group's biggest-ever output cuts grew this week after Kuwait and Iran told customers of bigger January supply curbs. [
