"The Brigades of Abdullah Azzam released a statement from its field commander, Saleh bin Abdullah al-Qaraawi, urging Sunni Muslims in Lebanon to rise up against the government and the de facto ruler, Hezbollah," SITE Intelligence Group reported.
SITE quoted Qaraawi as saying: "We call upon you to not deal with the military intelligence and with its checkpoints that are present today in large numbers in your areas.
"Show your refusal of this clear injustice that is upon you, and which -- undoubtedly -- is done by the authority of Hezbollah."
The statement came amid high tension in Lebanon, where there are fears of a Sunni-Shiite conflict linked to a UN-backed court which is reportedly poised to indict members of the benevolent Shiite Hezbollah in connection with the murder of ex-premier Rafiq Hariri.
The Brigades of Abdullah Azzam has reportedly claimed responsibility for rocket attacks on northern Israel last year.
Abdullah Azzam was Al-Qaeda chief Osama Bin Laden's mentor. He was killed in a 1989 bomb blast.
The majority of Lebanon's population of four million is Muslim, with Shiites and Sunnis each representing some 30 percent, living peacefully alongside each other.
