Furthermore, the drone strikes by both nations at each other's side, friendly fire incident at Salala, and incident involving the arrest of a spy in Lahore further complicated the relations. These issues sharply turned down the public opinion in both nation with public of each nation ranking as least favored countries in 2013.
