**The US Federal Reserve has repeated its pledge to keep interest rates at record lows in order to nurture the economic recovery.**The Fed said its main interest rate would be kept at the current 0% to 0.25% range, as widely expected.
Its rate-setting committee said that data on the US economy painted a mixed picture of the recovery from recession.
That meant rates would remain at “exceptionally low levels… for an extended period”, the committee said.
