Washington responds to ’Bin Laden tape’
White House adviser David Axelrod also said that the US could not confirm the authenticity of the audio tape.
The tape warned US President Barack Obama there would be more attacks if the US continued to support Israel.
In the tape aired by al-Jazeera, the speaker said US would not live in peace until there was "peace in Palestine".
The message also claimed that al-Qaeda was behind the 25 December attempt to blow up a passenger plane bound for the US.
A Nigerian man, Umar Farouk Abdulmutallab, has been charged with attempting to blow up the Delta Airlines plane as it approached Detroit from Amsterdam.
’No safe life’
Mr Axelrod told CNN the US could not immediately confirm the authenticity of the tape.
"But assuming that it is him [Bin Laden], his message contains the same hollow justifications for the mass slaughter of innocents that we’ve heard before," he said.
Israeli foreign ministry spokesman Andy David told Associated Press news agency: "This is nothing new; he has said this before. Terrorists always look for absurd excuses for their despicable deeds."
And in London, UK Foreign Secretary David Miliband said he needed to study the message, but pointed to the importance of the Detroit plot as "an attack on the West rather than an attack within the Middle East".
However, the head of the United Nations al-Qaeda monitoring team later told the BBC he believed the tape was genuine.
Richard Barrett said that there were "other, previous tapes that it can be compared with and I think it’s quite straightforward on basic voice analysis to decide whether it is indeed Osama Bin Laden".
"And I would imagine in this case that it will be."
’No safe life’
The voice recording said that the message was from "Osama to Obama".
Directly addressing Americans, it said: "It is unfair you enjoy a safe life while our brothers in Gaza suffer greatly... Our attacks will continue as long as you support Israel."
It went on: "America will never dream of security unless we will have it in reality in Palestine."
The Washington-based IntelCenter, which monitors terror group communications, said the message was a possible indicator of an attack within the next 12 months.
’Hero’ Abdulmutallab
In a reference to the plane plot, the message said: "If it was possible to carry our messages to you by words we wouldn’t have carried them to you by planes."
It said: "The message sent to you with the attempt by the hero Nigerian Umar Farouk Abdulmutallab is a confirmation of our previous message conveyed by the heroes of September 11."
Umar Farouk Abdulmutallab allegedly tried to set off a bomb hidden in his underwear but it failed to explode. He said he had been trained by al-Qaeda in Yemen.
The al-Qaeda in the Arabian peninsula group has already claimed it was behind the Christmas Day attempted bombing.
The BBC’s Kim Ghattas in Washington says the message may cast some light over the inner workings of al-Qaeda and its affiliates.
Some US intelligence officials said the tape was an attempt by the al-Qaeda leader to portray himself as in direct command of the organisation and all its offshoots.
Analysts have long debated whether Bin Laden is really in control, our correspondents says.
The al-Qaeda leader issues sporadic tape messages, the last being in September 2009 when President Obama was warned he was "powerless" to stop the wars in Iraq and Afghanistan.
The last purported Bin Laden video appeared in September 2007, when he referred to French President Nicolas Sarkozy and British Prime Minister Gordon Brown, who had both recently come to power.
