'Rana's US trial may unmask Pakistanâ€™s links to terrorists' WASHINGTON: The trial of Pakistan-born Canadian businessman Tahawwur Hussain Rana for his role in the Mumbai terror attack starting in Chicago on Monday. This could unmask Pakistan's links to terrorists, according to US media reports. Although only Rana is on trial, it's the story of his Pakistani American high-school friend David Headley, who has turned prosecution witness after pleading guilty to his own role in the November 2008 attack, proving damaging for Islamabad. "What he discloses could deepen suspicions that Pakistani spies are connected to terrorists and could potentially worsen relations between Washington and Islamabad," the 'New York Times' reported. Two years before terrorists struck Mumbai, "Headley began laying the groundwork for the attack, financed, he claims, by $25,000 from an officer in Pakistan's powerful ISI." "Headley told Indian investigators that the officer, known only as Major Iqbal, 'listened to my entire plan to attack India.' "Another officer with the intelligence service, the ISI Directorate, assured me of the financial help," Headley was quoted as saying by the 'Times'. "The US government's view of Headley â€” like so much else surrounding the ISI â€” was murky," said an unnamed American official cited by the 'Times'. "No agreement exists in Washington on whether the ISI guided Headley and the attacks on Mumbai. It's not very clear," the official was quoted as saying. The Wall Street Journal said Headley is expected to testify that the ISI was directly involved in plotting 26/11, carried out by LeT.
