CHETRY: Fifty-three minutes past the hour. A developing story now, a U.S. citizen now facing charges this morning for allegedly helping with the planning of last year's terrorist attack in Mumbai, India. A 160 people were killed; among them six Americans. Justice department now focusing on a man from Chicago who allegedly attended terrorist training camps in Pakistan. Drew Griffin of CNN special investigations unit has more on an American terror suspect.</s>DREW GRIFFIN, CNN INVESTIGATIVE UNIT CORRESPONDENT (voice-over): It was a well-planned assault on two Mumbai hotels; a Jewish center, a cafe, and Mumbai's train station. Gunmen racing in, killing as they went, then holding off police for two days, as the hotels burned, and victims were trapped inside. For the last year, India has pointed the finger at Pakistan, and the Kashmir terror group, Lashkar-e-Taiba, the so-called army of god. Now the U.S. attorney in Chicago says one of two men arrested earlier this year in connection with another conspiracy was involved in the Mumbai attacks. David Headley faces charges of aiding and abetting the murder of six U.S. citizens killed in those Mumbai attacks and conspiracy to bomb public places in India. Headley, a U.S. citizen born in Pakistan but grew up in Philadelphia, is charged with using his status as an immigration consultant to help plan and carry out the attacks in India. Headley already faces charges along with two others of planning an attack against the Danish newspaper that published cartoons of the Prophet Muhammad as well as an editor and cartoonist at the paper. The FBI says Headley is cooperating with its investigation but would not cooperate with Indian investigators. CNN has learned, once President Obama pledged cooperation with India, FBI agents from Chicago flew to Mumbai to aid in the investigation. Those agents are right now in India, working alongside Indian intelligence. According to court papers filed in Chicago, Headley conducted surveillance and took video of the Mumbai targets then met with the conspirators in the months before the November 26th attack.</s>GRIFFIN: A source close to the investigation is telling CNN that at the time of Headley's arrest, just this past October, FBI agents believed Headley was planning a second attack in India. We reached out to Headley's attorney who does confirm that his client is cooperating with the FBI but says he will not comment any further on the additional charges.
