RIP to the dead. I am worried that anti-Shia groups like the LeJ might be working with Jundullah & others, & providing them with support & reinforcements. These groups unfortunately seem to be gaining a lot of momentum, & it is happening openly in front of everyone's eyes. According to the Express Tribune, Jundullah has taken responsibility for this attack (although that is strange, as they operate in South West Balochistan). Express Tribune has also claimed they were dressed up in Army uniform, which is again very strange.
I have no doubts in my mind that there are fierce "intelligence games" being played in Western Pakistan, & now that the Iran-Pakistan economic/political cooperation is on the rise, "outside influence" might aid Jundullah & other groups to escalate their violence inside both Pakistan & Iran, acting as a spoiler. The Pakistani intelligence needs to get its act together, it feels like they are losing their sway, & losing their way a bit. Even though the ISI has an image of being ruthlessly good at what it does, I feel that is overrating their performance, & they definitely need to get their act back together. While they have done an ok job over the years, they need to shore up the country's defenses from such threats. They also need to clamp down on local sectarian groups like the LeJ that might support sectarian groups like Jundullah & al-Qaeda.
As a Pakistani Shia Muslim, while the incident itself is heartbreaking & disheartening, I am more interested/worried about the performance of our security/intelligence personnel in countering such future threats, & protecting the interests of Pakistan (both internally & externally).
