WASHINGTON, Nov 13: US President George Bush on Wednesday said experts were analysing an audiotape broadcast on the Al Jazeera television network purported to contain the voice of Osama bin Laden.

“Nevertheless, the contents of the tape, the message, is a serious message, and it should remind all of America and remind our friends and allies that there is a active enemy that continues to hate, is willing to use murder as a way to achieve their goals,” Bush said.

The president made his comments after a cabinet meeting and hours before he was set to hold talks with UN Secretary-General Kofi Annan over last week’s security council resolution on Iraq.

Bush said news of the taped message proved the “war against terrorism” was not over.

“Whoever put this tape out has put the world on notice yet again that we’re at war and that we need to take these messages very seriously. And we will,” Bush said.
