BCCI is just making dumb claims. They are just trying to create a problem at this point in my opinion. Obviously there are some issues that they do not want people to talk about. So they are trying to divert the interest of people to other things.
I do not think Jay Shah actually has any problem with the tournament being hosted in Pakistan. He is just trying to create an issue so that people concentrate on that issue a lot more. And people do not have any idea what is actually going on. Obviously ICC will be held accountable if they change the venue for the Asia cup at this moment. So I do not think ICC is willing to do anything like that.
