Now That OBL's Dead, Will al-Qaeda Unleash 'Nuclear Hellstorm?' Wikileaks Says 'Yes

The mastermind behind the 9/11 terror attacks Khalid Sheikh Mohammed promised that if Osama bid Laden was captured, al Qaeda would "unleash hell," according to the recent Guantanamo interrogation documents released by Wikileaks.

According to MSN news site Ninemsn.com, "hell" would come in the form of a nuclear bomb in Europe:

The mastermind of the 9/11 attacks warned that al-Qaeda has hidden a nuclear bomb in Europe which will unleash a "nuclear hellstorm" if Osama bin Laden is captured, leaked files revealed.

The terror group also planned to make a 9/11 style attack on London's Heathrow airport by crashing a hijacked airliner into one of the terminals, the files showed.

Khalid Sheikh Mohammed told Guantanamo Bay interrogators the terror group would detonate the nuclear device if the al-Qaeda chief was captured or killed, according to the classified files released by the WikiLeaks website.

Sheikh Mohammed, the self-professed mastermind of the September 11, 2001 attacks on the United States, has been held at Guantanamo since 2006 and is to be tried in a military court at the US naval base on Cuba over the attacks.

His nuclear threat was revealed in Britain's Daily Telegraph newspaper, one of several media outlets which have published the classified assessments of detainees at Guantanamo.
