Ulster Bank says a glitch that left some customers unable to view their transactions has been fixed.

A number of people were accidentally overdrawn yesterday after money disappeared from some accounts.

Ulster Bank says that all transactions impacted by the issue have now been applied -  and is ensuring that no customers will be left out of pocket.

Senior executives from Ulster Bank will be asked to appear before the Oireachtas committee on Finance & Public Expenditure to answer questions about the problem, which the bank has blamed on "human error".
