Ammon News - AMMONNEWS - The leader of Lebanese group Hezbollah described the radical Islamist movement that has seized territory in Iraq and Syria as a growing "monster" that could threaten Jordan, Saudi Arabia, Kuwait and other Gulf states.

Sayyed Hassan Nasrallah, whose group has been helping Syria's President Bashar al-Assad fight a Sunni Islamist-dominated insurgency, said the Islamic State of Iraq and Syria (ISIS) could easily recruit in other areas where its hardline ideology exists.

"Wherever there are followers of the ideology there is ground for (ISIS), and this exists in Jordan, in Saudi Arabia, in Kuwait, and the Gulf states," Nasrallah said in an interview with the Lebanese newspaper Al-Akhbar published on Friday.

Nasrallah, whose group is backed by Shiite Muslim power Iran, said ISIS was encountering resistance in some parts of Iraq and Syria. But he added: "It appears that the capabilities, numbers and capacities available to (ISIS) are vast and large. This is what is worrying everyone, and everyone should be worried."

Saudi Arabia, Which has been in a state of cold war with Shiite Iran and its allies, has shown growing signs of alarm about the spread of ISIS. Last month, it deployed 30,000 soldiers at its border with Iraq.

Saudi Arabia has also been a major sponsor of the anti-Assad uprising.

Hezbollah's role in Syria has helped Assad beat back the rebellion against his rule in critical areas of the country including Damascus and a corridor of territory stretching north from the capital. But large parts of Syria's less densely populated north and east have fallen to ISIS.

"This danger does not recognise Shiites, Sunnis, Muslims, Christians or Druze or Yazidis or Arabs or Kurds. This monster is growing and getting bigger," said Nasrallah.

Nasrallah reiterated his defence of Hezbollah's role in the Syrian conflict, the focus of criticism from Lebanese opponents who say the group has provoked Sunni militant attacks in Lebanon.

Most recently, insurgents including members of ISIS seized the town of Arsal at the Syrian border, battling the Lebanese army for five days before withdrawing with 19 soldiers and 17 policemen as captives.

Nasrallah said the insurgents would have advanced as far as the Lebanese coast were it not for Hezbollah's role fighting them in areas of Syria just east of the Lebanese border.

"Going to fight in Syria was, in the first degree, to defend Lebanon, the resistance in Lebanon, and all Lebanese," he said.

A Hezbollah commander was last month killed in Iraq near Mosul, a city seized by Islamic State in June, suggesting the group may also be helping pro-government forces there.

Hezbollah has not officially announced any role in Iraq.

Nasrallah linked the threat posed by ISIS to the spread of Wahhabism, a puritanical school of Islam followed in Saudi Arabia that demands obedience to the ruler but which has been widely blamed for fuelling Sunni radicalism.

"(Islamic State) does not have borders. There is a real danger and a real fear among many states and authorities, because one of the advantages of this organisation is its capacity to recruit among followers of al Qaeda-Wahhabi thought," he said.
