Afghanistan on Thursday hit back at Pakistan after a shrine bombing killed at least 55 people in Kabul, saying it was up to Islamabad to act after a Pakistani group purportedly took responsibility.
Pakistan on Wednesday urged Afghanistan to provide evidence to support claims that militant group Lashkar-e-Jhangvi was behind the attack after President Hamid Karzai demanded justice.
But in a developing war of words between the neighbours, whose relations are frequently tense, Kabul said on Thursday it was up to Pakistan to investigate without waiting any longer. "It was the Lashkar-i-Jhangvi which claimed responsibility," Aimal Faizi, Karzai's spokesperson said.
"It's up to Pakistan to take action."
