"My apologies to all the members of the Croatian people whom someone made unhappy in the name of my people. I am making them and assume the responsibility," HTV's prime time news on Saturday showed Tadic as saying.
The talk show was taped on Thursday and will air on Sunday at 2 pm. Tadic also spoke about the Kosovo issue, war crimes fugitive Ratko Mladic and the future of Croatia-Serbia relations.
He arrived in Zagreb to attend the Southeast Europe Energy Summit on Sunday.
