WASHINGTON - The number of U.S. workers filing new claims for jobless benefits fell last week to 570,000, and those collecting long-term unemployment benefits dropped to the lowest level since April, government data showed on Thursday.

Analysts polled by Reuters had forecast new claims slipping to 565,000 in the week ending August 22 from 580,000 the prior week, which had been previously reported as 576,000.

Continued claims fell to 6.133 million in the week ended August 15 from 6.252 million the prior week. That was the lowest since the week ending April 4, when they were 6.045 million.
