New Delhi, Jan 26 (ANI): Bangladesh has been infiltrated by a number of terrorist modules in the recent past. But a recent arrest of Tehrik-i-Taliban Pakistan (TTP) operatives in Dhaka, according to Sushant Sareen, a security expert at the Institute of Defence Studies and Analysis in Delhi, is an accomplishment of the Awami League government. Though, Sareen said that the presence of TTP operatives inside Bangladesh was a rare incident. The defence expert further said that the agitations carried on by theses terrorist outfits are an effort to create passion in Bangladesh against the ongoing war crime trials. And that they are somewhere supported by the western countries like US and UK.
