Both conjoined twins die
"Iranian sisters Iranian Laleh and Laden Bijani died today, more than 48 hours into marathon surgery to separate the 29-year-olds who had been born joined at the head...."

So both of them died...I just had wished the operation to go good & these two girls to be healthy & happy, living separated but now that they're dead I don't feel sad (as I never feel sad for the death of anybody); I'm sure that at the time they are much more happier than the time they were alive in this world. Anyway, I read in news that they died just a bit after they got separated; so it was their destiny to be joined; separation meant death to them.
