I wish there was a better way to deal with these kinds of attacks on civilians.

Religious lunatics like these are not deterred by the risk of being killed, it's literally a reward in their eyes. Violence is also just a crummy way to resolve problems.

Something like capturing them and making them work in the communities they targetted, to make them see that these people they want to kill are regular people just like themselves, and hopefully eventually realise that it's better to work for peace and heaven in this life, rather than destroying yourself on a promise of heaven in the next.

I know it's a stupid daydream that would never work in practice, but I just don't see an end to the killing right now.
