Absi ( pictured) accused Sunni leaders of being "traitors" and receiving orders from the Bush administration. He also said Hezbollah launched a sectarian war in May when it took over West Beirut.
"One is taking orders from [US President George] Bush, and the other from the devil's verses in Tehran," he Absi said
He hinted it was time for revenge and that Iraq's bombings and suicide bombers would not spare "God's enemies wherever they are."
The authenticity of the audiotape could not be independently verified but was posted on websites which issue statements by extremists.
If the tape is proven to be authentic, it would be the second since the leader of the terrorist group escaped from the northern Palestinian refugee camp of Nahr al-Bared last year.
Absi is believed to have escaped from the camp during bloody gunbattles between the Lebanese army and Fatah al-Islam fighters which led to the death of 400 people, including 137 Lebanese soldiers.
The more than three-month siege at the camp destroyed large parts of the shantytown.
Earlier this year, the fugitive leader lashed out at then army chief Gen. Michel Suleiman and vowed his fighters would hunt down the current president's followers whom he accused of destroying Nahr al-Bared as part of a deal to become head of state.
The al-Qaida-inspired group's leader also accused Suleiman in his first audiotape of waging the battle at the camp for political purposes, including appeasing the United States.
In the new tape headlined "An Appeal to Lebanon's Sunnis," Absi criticized the army which many accused of siding with the opposition during the May clashes and said the military "disappointed" Sunnis who backed it during the Nahr al-Bared battles.
In a related development Fatah Secretary in Lebanon Sultan Abul Ainein said Palestinian refugees have reached an unanimous agreement to prevent wanted or suspicious foreigners from residing in the Ain al-Hilweh Palestinian Refugee camp so that it wouldn't be a second Nahr al-Bared.
Abul Ainein addressing a press conference at his office in the southern refugee camp of Rashidyeh, said the agreement was reached among the various Palestinian factions to consolidate security at Ain al-Hilweh, located on the southern edge of the southern city of Sidon.
"All Palestinian factions are convinced that any person who could be a source of concern should not be allowed into the camp," Abul Ainein said.
"This is what has happened in fact. A man believed to be a citizen of a gulf state has been deported ... after the killing of a man carrying an explosive belt, who is believed to be a Saudi citizen," he added. 
He was alluding to the would be suicide bomber ( pictured) who was killed by the army as he was trying to blow himself up .
On Tuesday, the Lebanese Army Command - Orientation Directorate released footage of the would be suicide bomber who was wearing an explosives charge belt loaded with two kilograms of TNT and a kilogram of metal balls.
