Who, or what, is 'Khorasan'?

A little-known Al Qaeda offshoot, Khorasan found itself in the crosshairs of the United States on Tuesday as the extremist outfit finalised imminent attacks on Western targets from bases inside Syria.

With militants terrorising the region and seizing large chunks of Iraq and Syria, it came as a surprise to many that the Pentagon aimed its Tomahawk cruise missiles and other firepower not just at militant positions, but at a far smaller band of former Al Qaeda operatives in northwestern Syria who had largely operated in secret.

The Khorasan group's under-the-radar status was obliterated overnight.

The Pentagon accused Khorasan of planning "major attacks" against the West, saying it had eliminated the group's militants who were in the "final stages" of plots to wreak havoc against Europe or the United States.

The group -- led by a former Osama bin Laden cohort and including veteran operatives -- is not new, experts and President Barack Obama's administration said.

Officials were so concerned about the group that new restrictions for passengers on US-bound flights were imposed in July to prevent a possible attack, Attorney General Eric Holder told Yahoo News.

The previously little-known organisation's plots, reportedly discovered in the past week, included using a bomb made of a non-metallic device like a toothpaste container or clothes dipped in explosive material, CNN reported, citing an intelligence source.

Deputy National Security Advisor Ben Rhodes described the group as including "core Al Qaeda operatives from Afghanistan and Pakistan who made their way to Syria," and that the Pentagon acted because it believed attacks against western targets were "imminent”.

The Pentagon said a majority of the 40-plus Tomahawk cruise missiles launched into Syria were aimed at the Khorasan lair and training camps near Aleppo.

Action against Khorasan had long been considered and was "separate and apart from the growing threat," a senior US official said.

Matthew Henman, who heads IHS Jane's Terrorism and Insurgency Center, said Khorasan's warriors slipped into Syria to link up with the Al Nusra Front, Al Qaeda's affiliate in the war-torn country.

Its funding and weaponry are limited, but Khorasan came "to exploit the vacuum and the very chaotic situation in Syria," Northeastern University professor Max Abrahms, who is also a terrorism analyst at the Council on Foreign Relations, told AFP.

'Like a hyena'

By preying on the chaos and destruction in Syria, and less interested than militants in seizing territory, "Khorasan is like a hyena which basically picks up pieces of carcasses" in a brutalised landscape, Abrahms said.

Its maximum 1,000 members pale in comparison with the estimated 31,000 Daesh fighters.

Khorasan leader Muhsin Al Fadhli is believed to have had close ties to Al Qaeda founder bin Laden, and the group should be considered an Al Qaeda affiliate "in more international-minded terms" according to Abrahms.

"The fact that the US targeted the Khorasan group in the very first wave of attacks really underscores how seriously the US takes this group," he said.

In brief remarks, Obama bluntly justified attacking Khorasan bases: "We will not tolerate safe havens for terrorists who threaten our people."

Lieutenant General William Mayville, director of operations for the US Joint Chiefs of Staff, said the group "is clearly not focused on the Syrian people" or the regime of Bashar Al Assad.

"They are establishing roots in Syria in order to advance attacks against the West," he said, warning that Khorasan was recruiting foreign fighters who could use their western passports to return to their countries and carry out attacks. Agencies
