Strike leaves BNP branches in Belgium short of cash

* Quarter of BNP cash machines in Belgium have no cash

* Strike by delivery firm also hits Delhaize supermarkets

BRUSSELS, Nov 12 (Reuters) - One of the biggest banks in Belgium had run out of banknotes at a quarter of its cash machines on Friday as a strike at money delivery firm Brink's (BCO.N) choked supply.

A spokeswoman for the bank, French-owned BNP Paribas (BNPP.PA), said the shortage had also left half of its 247 cash machines that are not in bank branches with no notes.

The bank operates about a quarter of all cash machines in Belgium.

Workers at the Belgian arm of U.S. cash delivery company Brink's have been on strike for the last two weeks over plans to change their legal status and to close down a site in Belgium.

Delhaize (DELB.BR), one of Belgium's three biggest supermarket chains, said it had started asking customers to pay by card at some of its shops because it was running short of cash due to the strike. A spokeswoman for Delhaize did not say how many shops were affected.

Financial services group ING Groep NV (ING.AS), which also uses Brink's in Belgium, said it was seeing little impact from the strike.

Brink's was not immediately available for comment. (Reporting by Ben Deighton; Editing by Susan Fenton)
