Applications for unemployment benefits soared to the highest level since just after the Sept. 11, 2001, terrorist attacks while the trade deficit shrank more than expected as demand for imports plunged, further evidence of the struggling U.S. economy.

The Labor Department reported Thursday that jobless claims shot up by 32,000 last week to a seasonally adjusted 516,000, the highest total in seven years. The tally was much higher than analysts expected and a further indication of how much the labor market is deteriorating amid the shrinking economy. The government reported last week that the unemployment rate surged to a 14-year high of 6.5 percent in October.
