The Al-Qaeda chief warned US President Barack Obama was "still walking in the footsteps" of his predecessor, George W. Bush, by escalating the war in Afghanistan.
Bin Laden also condemned Obama for "oppressing our prisoners that you are holding, beginning with the mujahid (holy warrior) hero Khaled al-Sheikh Mohammed."
US politicians, he added in the audiotape, had "oppressed us and still do, especially by backing Israel, which occupies the land of Palestine," said the Al-Qaeda chief.
The United States is just weeks away from a landmark decision on whether to try Sheikh Mohammed and his four alleged co-conspirators in a civilian federal court or in a military tribunal.
The Obama administration had announced it would them at a courthouse in New York, just steps from where the World Trade Center that collapsed in the 2001 attacks had once stood.
But the plan for the trial met a backlash from Republican lawmakers who have introduced legislation to require a military trial, throwing a challenge to Obama months ahead of mid-term elections in November.
Obama made bringing Sheikh Mohammed to a civilian trial a centrepiece of a broader plan to end what he saw as serious abuses of law in the time of Bush and his powerful vice president Dick Cheney.
Bin Laden's latest statement was his first since January, when he claimed responsibility for the botched Christmas Day bombing of a US airliner and vowed further strikes on American targets.
Bin Laden also referred to US support for Israel in the January message.
"God willing, our attacks against you will continue as long as you maintain your support to Israel," he said.
"America should not dream of security until we enjoy it as a reality in Palestine," said the Al-Qaeda chief, who has a 50-million-dollar bounty on his head.
