As the Times Square failed bombing suspect Faisal Shahzad told investigating agencies of attending a terrorist training camp in Pakistan's Taliban affected Waziristan, an eminent US expert has suggested the federal investigators to focus on his five-month stay in the troubled nation.
"The focus of the investigations needs to turn to Shahzad's activities during his five-month stay in Pakistan, which may have been critical in both motivating and technically preparing him to carry out the attempted attack," said Lisa Curtis of the Heritage Foundation, a Washington-based think tank.
Curtis pointed that previous terror attacks and bids on the US, India and European nations had "connections to Pakistan-based terrorist groups and individual."
"Given the increasing fluidity of group membership and cross-pollination of the various terrorist groups operating inside Pakistan, it may take time for investigators to discern exactly with whom he may have been working and what was his primary motivation for carrying out the attempted bombing," she said.
While saying it is "early" to speculate on Shahzad's international terrorist networks, Curtis emphasised that the US should "work closely" with Pakistan to "to run down any leads" in that country.
