Eleven people were killed Saturday when two vans carrying a polio vaccination team were hit by a roadside bomb in Pakistan 's northern Khyber Agency , authorities said . Among the dead was an 8-year-old child ; 12 other people were wounded , Khbyer Agency surgeon Dr. Rehman Khan said . Ten of the fatalities were tribal policemen called Khasadars , he said . Though the security forces and militants engaged the attackers in a gun battle , the militants escaped , he said . The child was caught in cross-fire , said Dr. Sameen Jan Shinwari , medical superintendent of Agency Headquarters Hospital in Jamrud . The Khyber Agency is a loosely governed tribal region that borders on Afghanistan . Pakistan 's military had resumed operations against suspected Taliban strongholds in Khyber and other nearby agencies , after peace talks with the militant group broke down last month in the wake of attacks by the group . Earlier this week , government airstrikes demolished suspected Pakistani Taliban hideouts in Waziristan and may have killed dozens , the military said . But , after Saturday 's attack in Khyber Agency , the Pakistani Taliban announced a month-long cease-fire , the group 's spokesman , Shahidullah Shahid , told CNN . A government spokesman said the committee charged with holding talks with the TTP welcomed the announcement as a `` positive development , '' but had received no official cease-fire offer . The government 's committee is expected to meet early next week to discuss the development . A militant group , which has connections to the Pakistani Taliban , opposes polio vaccinations , accusing polio workers of pursuing a political agenda . Anti-polio campaigns have been targeted by militants in Pakistan since U.S. intelligence officials used a fake vaccination program to help in their hunt for Osama bin Laden in 2011 . Under cover of the program , the CIA sought to collect DNA samples from relatives of the al Qaeda leader to verify his presence in a compound in Abbottabad . Since July 2012 , at least 22 polio workers have been killed . The polio campaign has a history of controversy in Pakistan . Some mullahs have preached against it , claiming falsely that the oral vaccine leaves Pakistani children sterile . Last year , a Taliban commander in northwest Pakistan announced a ban on polio vaccines for children in the region as long as the United States continued its campaign of drone strikes . Polio , which can cause permanent paralysis in hours , remains endemic only in Pakistan , Nigeria and Afghanistan .
Among the dead : an 18 - old boy . Pakistani Taliban announce a week - long cease - fire . Security forces and militants fire upon each other . Two vans carrying a polio research team are hit by a roadside bomb .
