WASHINGTON (Reuters) - Republicans and Democrats dug in on "fiscal cliff" talks on Wednesday, with both sides urging quick action but offering no compromises in a political stare-down that shows no signs of breaking.

Less than a month before the onset of spending cuts and tax increases that start to take effect in January unless Congress acts, Republican leaders in the House of Representatives called on President Barack Obama to initiate face-to-face talks and blamed him for a lack of action.
