LAHORE: Pakistan Awami Tehreek (PAT) and Pakistan Tehreek-e-Insaf (PTI) have on Wednesday jointly refused to cooperate with the administration and the police, leaving the sit-in protest exposed to direct security threat. According to reports, the two parties have refused to accept bullet-proof rostrum and have also asked the police to remove the mobile jammers as well as the security containers. The move has left the sit-in completely exposed to the threat of terrorist attacks as the parties are not ready to cooperate even for the security and safety of the sit-in participants.
