Conversation so far:
What were Gulbuddin relations with the Taliban?
Moreover, the agreement was clearly not what the Pakistanis wanted, and convinced them of Hekmatyar's weakness, and that they should shift their aid entirely over to the Taliban.
What happened after they shifted their aid to the Taliban?
The Taliban responded to the agreement with a further spate of rocket attacks on the capital.

Question: When did this attack happen?
Self-contained rewrite: When did The Taliban's attacks happen?
