The number of Americans filing initial claims for jobless aid rose a sharper than expected 30,000 last week, the biggest jump in over a year.

First-time claims for state unemployment benefits climbed to 360,000 in the week ended April 10, their highest level since early February, from a revised 330,000 in the prior week, the Labor Department said.

Wall Street economists had expected claims to rise to only 335,000 from the more than three-year low reached in the previous week.

In other economic news, factories in New York state saw business conditions improve markedly in early April, more than reversing a slowdown suffered the month before, a survey said on Thursday.

The Federal Reserve Bank of New York said the business conditions index of its two-year-old Empire Manufacturing Survey rose to 36.05 in April from 25.33 in March, and back toward February’s record high of 42.05. Economists had expected a modest in the index to 26.8.
