They call him a "house negro"...u gotta love AQ. This is the guy we really would love to wack.
The second-in-command of Islamic militant network al-Qaeda has hit out at US President-elect Barack Obama.
In a message purportedly from Ayman al-Zawahiri, the al-Qaeda deputy called Mr Obama a "house negro" - a demeaning term implying he served white people.
Mr Obama's plan to bolster the US military presence in Afghanistan would fail, Zawahiri said.
If genuine, the message would be the first acknowledgement by al-Qaeda of the president-elect's victory.
The audio message appeared on militant websites.
Zawahiri, an Egyptian by birth, is often referred to as Osama Bin Laden's right-hand man and the chief ideologue of al-Qaeda.
In the short message he warned Mr Obama of failure if he followed Bush administration policies in the Middle East and Afghanistan.
He also criticised Mr Obama - whose father is Muslim - for abandoning his Islamic roots.
"You were born to a Muslim father, but you chose to stand with the enemies of Muslims," he said.
On Sunday, in his first television interview since his 4 November election win, Mr Obama reiterated his commitment to shift more US troops to war-torn Afghanistan.
Stamping out al-Qaeda "once and for all" was a top priority, he said, and capturing or killing Osama Bin Laden was "critical" to US security
