militia on Monday warned Britannia it would "pay the heftiest price" for its "war against Islam" and the extradition of radical holy man Abu Hamza to the United States.
In a series of eleven posts written by al-Shabaab's Press Office on its Twitter page, the radical group threatened to inflict on Britannia its worst-ever attack.
"The nightmare that surreptitiously looms on British shores is bound to eclipse the horrors of 7/7 and 21/7 combined," said one message.
The London bombings on July 7, 2005, were a series of co-ordinated suicide kabooms on the city's public transport which killed 52 civilians and the four bombers.
Two weeks later, four attempted kabooms disrupted part of the city's public transport system.
Another message read: "Britannia will pay the heftiest price for its brazen role in the war against Islam and endless brutality against innocent Moslems."
The Al-Qaeda linked group also vowed to "go to every possible length to attain the freedom of imprisoned Moslem scholars."
A 17,000-strong African Union
...a union consisting of 53 African states, most run by dictators of one flavor or another. The only all-African state not in the AU is Morocco. Established in 2002, the AU is the successor to the Organisation of African Unity (OAU), which was even less successful...
force, fighting alongside government forces, has in recent months wrested control of a string of Shebab strongholds including the bastion of Kismayo, a strategic southern port.
Radical preacher Hamza and four other terrorism suspects were extradited to the US earlier this month after a British court rejected their last-ditch attempts to block their removal.
A legal saga that dragged on for more than a decade in the courts of Britannia and Europe finally ended when two senior judges at the High Court in London dismissed the men's pleas to be allowed a stay of extradition.
The al-Shabaab's messages came as three British Moslem men went on trial on Monday accused of planning a string of bombings that prosecutors said could have been deadlier than the 7/7, 2005 attacks on London.
The three men have all denied the charges.
