WASHINGTON (Agencies) - A Pakistani man living in the United States faces up to 15 years in jail after pleading guilty Friday to providing material support to the Lashkar-e-Taiba (LeT). US justice officials said Jubair Ahmad, 24, posted a propaganda video for LeT glorifying violent jihad in 2010, three years after he arrived in the United States with his parents and two younger brothers. Foreign terrorist organisations such as LeT use the Internet as part of well-orchestrated propaganda campaigns to radicalise and recruit individuals to wage violent jihad and to promote the spread of terror, said US Attorney Neil MacBride. Todays conviction of Jubair Ahmad demonstrates that we will aggressively investigate and prosecute anyone who provides material support to a terrorist organisation in whatever form it takes, he added. By preparing and posting a graphic video that glorified violent extremism, Mr Ahmad directly supported the mission of a designated terrorist organisation, said FBI assistant director in charge James McJunkin. Ahmad admitted he communicated with the son of the LeT leader, Talha Saeed, who asked him to make a video showing his father and include scenes of attacks in Kashmir. He made the video in September 2010 and posted it on YouTube. Ahmad, of Woodbridge, Virginia, close to the US capital Washington, will be sentenced on April 13.
