"A joint working group comprising relevant agencies of Afghanistan and Pakistan will address the recent attack on the National Security Director of Afghanistan," all three countries said in a statement. Pakistan had said it would assist in any investigation into the bombing, but had also urged Karzai to provide evidence before "levelling charges", and suggested Kabul look into any lapses in its own security plans that may have facilitated the attack.
While Karzai and his Pakistani counterpart Asif Ali Zardari put up a united front on Wednesday, both leaders were scant on details of their talks over the attack. Asked whether he had received the clarification he had wanted before the meeting, Karzai said: "We had very good conversations and we are not going to divulge details." Zardari declined to comment specifically on Karzai's allegations but said: "It is in the interest of Pakistan that Afghanistan prospers". Speaking to Reuters after the summit, Foreign Minister Hina Rabbani Khar said Karzai had assured the Pakistani side he had not specifically accused Pakistan.
