Two visiting US Treasury Department intelligence experts are assisting Bangladesh in detecting and routing sources and channels of funds to the Islamist militants. US Treasury Department's Financial Crimes Enforcement Network (FinCEN) Senior Research Analyst Mary Jo Melancon and Senior Intelligence Research Specialist Kristen J King, who arrived here last week, have already sat with Bangladesh Bank (BB) officials on Monday and Tuesday. Today they will illustrate and orient a select group of police, judicial, customs and central bank officials to how FinCEN operates to safeguard the US financial system from abuses and crimes like terrorist financing and money laundering, BB sources said. The Washington-Dhaka high-level cooperation to clip the wings of the Islamist terrors comes concurrently with the recent captures of the top two JMB masterminds and the government's inability so far to unearth the sources and ways of their funds. While Melancon and King were discussing strategies with BB officials to detect and prevent terror financing on Tuesday, the foreign minister was briefing the foreign envoys on the situation following the arrests of JMB supremo Abdur Rahman and his second-in-command Bangla Bhai.
