Pakistan says Jamaat-ul-Ahrar and the main Tehrik-e-Taliban Pakistan militant groups had been operating from Afghan areas near the Pakistani border and that Kabul in the past ignored Islamabad's pleas to take action against them. Shahbaz Sharif , chief minister in the eastern Punjab province , announced late Friday the arrest of a suspect in connection with the Feb. 13 suicide bombing. Pakistan wants immediate action by Afghan authorities, including the suspects' extradition to Islamabad.In Kabul, the Afghan government Saturday summoned Pakistan's ambassador in protest of recent shelling in Afghanistan's eastern provinces. Pakistani officials say the country sheltered 5 million Afghan refugees at one time and there are still an estimated 1.3 million registered and over a million more unregistered living in the country. We are waiting for the response through the diplomatic channels; otherwise we are fully ready to defend our country.
