There are quite a number of shias in ajk, some months back when there was a sudden onslaught of terror attacks all over pakistan , a shia cleric in azad kashmir was also targetted tho he survived. I have distant relatives from azad kashmir and they tell there are quite a shias there. I had once visited ajk when i was a kid and myself had seen a very huge moharram mourning procession where everyone was beating themselves with chains etc etc -as it was like any other procession in any other part of pakistan. so please do not speak stuff on your own.
Secondly , ayatollah is a corrupt mullah he could care less about palestinians , iranains just want their footprint all across arab land. if thee is anything iran has done for palestine than it is damage to palestinian cause through its terror proxies like Hizbollah. Trust me no syrians or palestinians would say we are happy with iran or need irans help, Instead they are sick and tired of iranian intervention. And normally palestinians ask pakistan army to help them,
Lastly, again please do not make up stuff on your own unless you know people from any specific region.
