London: A new video posted on extremist websites linked to al Qaeda has shown six masked assassins dressed from head to toe in black ``ninja`` outfits firing automatic pistols.
According to The Sun, it is feared the terror network, whose leader Osama bin Laden was killed by the US in 2011, intended a massacre in Britain or Europe like the 2008 attacks in Mumbai, India, that left 164 dead.
The video underlines the recent warning by MI5 chief Jonathan Evans that Al-Qaeda fanatics continued to pose a threat, the report said.
The ninja terrorists are filmed blasting AK-47 assault rifles, nicknamed the "Widowmaker".
Two of the black-clad recruits are shown with a heavy machine gun. Other terrorists are filmed rehearsing drive-by shootings from a pick-up truck and motorbike.
Their arsenal also includes rocket-propelled grenade launchers.
It is thought the training drills were recorded at a camp on the border of Afghanistan and Pakistan.
Terrorism expert Chris Dobson said: "Pistols are the weapon of choice for close-quarter murder, a favoured tool of the assassin".
"Al-Qaeda is showing that despite the battering they have taken in the past year, they are still a force," he added.
