Mumbai, September 2 (NDTV.COM) Intelligence Bureau officials are on the lookout for six members of the Armed Islamic Group (GIA), who they say have entered the country to carry out terror strikes in New Delhi and Mumbai.

The documents regarding them that were leaked from the Intelligence Bureau could present the new face of terrorism in India.

The GIA is a militant outfit that started out fighting to replace the Algerian government, but now has moved to a jihadi agenda and is said to have al-Qaeda links.

The intelligence agency has provided some details regarding some of the men.

The first is Abdullah Wabah, a Pakistani national, who was trained in Algeria. IB sources claim he's been schooled to assemble bombs in a matter of minutes.

The second man is Yasman Kadeera who is also a Pakistani national and has been trained as a special commando in Pakistan. He is a veteran who has fought many battles in Algeria and Yemen, and he is a trained sniper and an expert getaway driver.

The third name that was released was Kaleele Machyar, who is also a Pakistani national.

He, sources say, entered the country with other GIA members, but has now shifted allegiance to the al-Qaeda. Intelligence Bureau sources say that he could target Delhi Airport.

The last name is of a Hasan, who is a South African national. He, according to sources, is fluent in English and is said to be travelling with the men helping them with their jobs.

Route to India

IB investigators have still to figure out who the other two men are, but what they do know is how these men travelled to India.

According to intelligence sources, from Algeria, these men travelled to Niger and then to Burkina Faso and Mali, finally making their way into India.

They entered the country using false names and passports, and the first alert for the six men was issued on August 10th, warning of attacks in Mumbai and Delhi between August 11th and 15th.

But IB sources say that tight security ensured the men could not carry their mission.

The alert was re-issued on August 24th, which the IB says will stay in place till the men are found and captured.
