DUBAI, Nov 20 (Reuters) - Abu Dhabi's Union National Bank UNB.AD (UNB) said on Sunday it was not in any merger talks.

The bank issued the bourse statement in response to a Bloomberg news story last week, citing unnamed sources, that the Abu Dhabi government might engineer a merger between Abu Dhabi Commercial Bank ADCB.AD (ADCB) and Union National Bank UNB.AD (UNB), and another between Abu Dhabi Islamic Bank ADIB.AD (ADIB) and Al Hilal Bank.

In separate statements earlier on Sunday, ADIB and ADCB both denied they were in any merger talks. urn:newsml:reuters.com:*:nD5N1CO03X urn:newsml:reuters.com:*:nD5N1CO03W
