It is being called a terror attack but no group has so far claimed responsibility or been identified.
It could be a homegrown group or one supported from outside.
Either way it turns out, it is going to affect the talks.
Pakistan wants the Kashmir issue to be on the dialogue agenda while India wants to focus on “terrorism“.
In case the group or persons behind the attack turn out to be Indians, it will strengthen Pakistan’s argument that both countries are victims of such attacks and they should not be allowed to derail diplomacy.
In case the blast is linked to Pakistan, it will be seen as a provocation the Indian government, given political compulsions, would not like to be seen taking lying down.
