Kabul , Afghanistan ( CNN ) -- Afghan President Hamid Karzai has criticized the timing of the U.S. drone strike that killed the leader of the Pakistani Taliban last week , his office said in a statement . Karzai made the comments when he met with a U.S. congressional delegation in Kabul on Sunday evening , the statement said . The Afghan President expressed hope that the death of the Pakistani Taliban leader , Hakimullah Mehsud , would not undermine cooperation between Afghanistan and Pakistan aimed at achieving a successful peace process . Mehsud , who had a $ 5 million U.S. bounty on his head for his alleged involvement in a 2009 attack on a U.S. base in Afghanistan , was killed Friday in a drone strike in northwestern Pakistan , senior U.S. and Pakistani officials said last week . The Pakistani government condemned the use of drone strikes on its territory after Mehsud 's killing . The U.S. ambassador to Islamabad was summoned to Pakistan 's Foreign Ministry on Saturday . Mehsud 's death happened as Pakistani authorities were working on efforts to hold peace talks with the Pakistani Taliban . There are fears that his killing could jeopardize the proposed talks . In a different initiative , the Afghan government announced plans last week to send a delegation to Pakistan to meet with Mullah Abdul Ghani Baradar , a former Afghan Taliban leader who was released last month from detention by Pakistani authorities . The planned visit plays into efforts to pursue peace in war-torn Afghanistan , where NATO and Afghan troops have been fighting the Afghan Taliban for more than a decade . The Afghan Taliban condemned the drone strike that killed Mehsud as `` cowardly '' and `` barbaric '' in a statement posted on their website Saturday , the SITE intelligence group said . The statement urged the Pakistani government and people to take measures to stop the attacks . The Pakistani Taliban have voted to elect Asmatullah Shaheen , who is on Pakistan 's most wanted list , as their interim head , an official for the group said . The group , also known as Tehreek-e-Taliban Pakistan , will not be making an announcement on a new permanent leader for several more days , according to Azam Tariq , a member of the Pakistani Taliban 's Shura Council , their centralized decision-making body .

A U.S. drone strike in northwestern Pakistan killed Taliban last week . Pakistani officials plan to travel to Pakistan to meet a former Afghan Karzai leader .
