Well it started a way bit earlier then that
1- Psychological war fare started in UAE , with ban of 2 fan favourite players , immediately after it was announced Lahore will host the finals of the event which show cases Pakistan's talent. Najam Sethi fell for RAW tactics and immediately sent home players with no investigation , Demoralization was the goal
2- Secondary phase was target the actual city , where the fans/ Pakistani public wanted to converge for finals
So obviously coordinated attacks on police force to give an impression to masses that the cities are not
secure
3- Multiple cities were targetted and police force , a pattern used in Syria /Libya , weaken the Police force's moral and local safety first (Quetta / Tribal Areas / Lahore) , target 3 main cities to give an impression of lack of security
4 - Obviously on Line of control, there were act of shooting so RAW operatives / Afghan collaborators achived their objective
