Pakistan's Foreign Office has rejected President Hamid Karzai's claim that the assassination attempt on Afghan spy chief Asadullah Khalid was planned in Quetta.
The Foreign Office said that instead of blaming Pakistan, Afghanistan should investigate the security failure which gave the bomber a chance to infiltrate the high security zone area.
"Afghanistan should share information with Pakistan over the attack," the office said in a statement on Saturday, adding that Pakistan was ready to cooperate in the investigations.
Karzai on Saturday told reporters in Kabul that the bomber came from Pakistan and the plan was made in Quetta, like the suicide attack on the former head of the High Peace Council Burhanuddin Rabbani.
"Of course we will be seeking clarification from Pakistan because we know this man who came in the name of a guest to meet Asadullah Khalid came from Pakistan. We know that for a fact," said Karzai.
Karzai stopped short of blaming Pakistan itself. But he said the attack was too "professional" an attack for the Taliban.
"Apparently the Taliban claimed responsibility like many other attacks, but such a complicated attack and a bomb hidden inside his body, this is not Taliban work. It's completely professional," he said. "Taliban cannot do that and there are bigger and professional hands involved in it."
He said that it will not affect the fledgling peace talks recently revived with Pakistan, and the matter will be discussed next week with Pakistani officials during a meeting between the foreign ministers of Afghanistan, Pakistan and Turkey in Ankara.
Khalid survived the Thursday afternoon suicide attack at a National Directorate of Security guesthouse in Kabul, but received substantial injuries to the lower part of his body. He is being treated in Bagram airfield hospital.
