In an operation smaller than the much larger US operation that monitored Osama bin Laden and his Al Qaeda guests in Abbottabad, Pakistan, from 2005 to 2011 (then international exploitation of the intelligence gained):
PETE COMMENT
INTELNEWSJULY 17, 2018reports:
“A joint Indian-American counterintelligence operation, described as “unprecedented in its scale and scope”, reportedly foiled a major suicide attack by the Islamic State in New Delhi and helped achieve “a string of victories” against the group in Afghanistan and Pakistan. Citing “top diplomatic and intelligence sources”, the New Delhi-based daily The Indian Express said that the “audacious” operation took place a year ago, but details about it were only made available to its reporters in recent days...”
Looking back again to Abbottabad - so many massive counter-terrorism operations continue for years below the surface. As ever, “discoveries” just a few months old that boost a US President’s (in 2011 Obama's) counter-terrorism credentials, actually concern operations of great value that lasted several years.
