As a massive search operation is on way in the dense forests of Poonch following a terror attack on an Army vehicle that left five soldiers dead and one critically wounded at Bhatta Durrian in Poonch on April 20, around 50 persons have been detained so far and the search has been intensified up to the Line of Control to ensure attackers don’t escape towards Pakistan Occupied Kashmir, officials say. However, no formal arrest has been made so far.
