From Ya Libnan:
Clashes in the south between the army and Jund al-Sham, another Sunni militant group, show that Fatah al-Islam already has sympathizers ready to take up arms in solidarity.
More may be recruited to such groups thanks to the spread of Sunni Islamist thought, especially in and around the northern city of Tripoli, which has long been a cradle for all types of political and militant Sunni Islam.
Fathi Yakan, a prominent Islamist from Tripoli, said hardliners may take up arms against the state "out of fear that their turn will come" after Fatah al-Islam.
"If they find that Fatah al-Islam is in trouble now, then these might act, perhaps they will cooperate with it, or even support it," said Yakan, leader of the Islamic Action Front -- one of the biggest Sunni Islamist groups in Lebanon.
"For this reason, the situation is getting more serious," said Yakan, listing the full range of Sunni Islamist schools of thought in Tripoli. They include the Salafi school that is linked to the Wahhabi beliefs followed by Osama bin Laden.
And this one on Abu Musab al-Zarqawi's old group, Al-Tawhid wal-Jihad:
In a Web statement, the group Tawhid and Jihad ( their full name is Jama'at al-Tawhid wal-Jihad ) in Syria promised its support for the camp's fighters. The Tawhid and Jihad leader, Abu Jandal al-Dimashqi, met with representatives from Fatah al-Islam recently, the statement said.
"We warn the Lebanese government that its vital interests, officials and sons living in Syria will be moving targets for us if it does not lift its siege off the camp," said the statement, posted on a Web forum where militant groups often issue messages.
"Let the Lebanese government wait for the hell of kidnapping, shooting and chopping of heads if it does not respond to the demand," said the statement. Its authenticity could not be verified.
Tawhid and Jihad in Syria first became known in November, when its former leader Omar Abdullah clashed with Syrian security forces and blew himself up on the border with Lebanon.
Al-Dimashqi then issued a May 28 audiotape claiming to be the group's new leader and calling on Syrians to kill Syrian President Bashar Assad and on other Arabs to topple their leaders as well.
"Tawhid and Jihad" -- Arabic for "monotheism and holy war" -- is a name used by several groups apparently inspired by al-Qaida -- though their actual links to Osama bin Laden are not clear. Al-Qaida in Iraq formerly went by the name. The most prominent militant group in Syria is known as Jund al-Sham, but it is sometimes called the Jund al-Sham for Jihad and Tawhid.
