ISLAMABAD , Pakistan ( CNN ) -- Pakistani armed forces have killed 80 militants since launching an assault on a region recently held by the Taliban , the military announced Sunday . Displaced people from Buner district flee the fighting . Three soldiers have been killed and eight wounded in the crackdown in the Buner district in the northwest of the country , the military statement said . The Pakistani offensive started in the province last Sunday , after Taliban militants moved into Buner , a move that alarmed U.S. and Pakistani officials . Pakistani security forces also killed at least 16 militants late Friday and early Saturday in the Mohmand district , in the country 's volatile tribal region , the country 's military said on Saturday . The incident appears to be separate from the hostilities in Buner . However , it reflects the tensions in the region and could signal a spread of fighting resulting from the crackdown . In the incident , about 100 militants attacked a Frontier Corps post in the Mohmand Agency , or district , an area where militants hold great sway . Troops returned fire and killed the 16 militants , the military said . Mohmand is in the country 's Federally Administered Tribal Areas that border a volatile region in war-torn Afghanistan and Pakistan 's North West Frontier Province . Earlier this year , Pakistan had entered into an agreement with militants , allowing them to enforce Islamic law , or sharia , in parts of Swat Valley in exchange for ceasing violence . The Swat Valley is a broader area that includes several provincial districts , including Chitral , Swat , Shangla , Malakand , Upper Dir , and Lower Dir . But Pakistani officials say the armed militants ' advance into Buner district violated the agreement and briefly halted peace talks between the two sides in North West Frontier Province . Representatives from Pakistan 's government and the Taliban restarted their negotiations on Friday and were planning to have another session soon , a provincial spokesman said . The Pakistani government has been criticized for not cracking down on militants along its border with Afghanistan . As a result , the U.S. military has carried out airstrikes against militant targets in Pakistan , which have rankled relations between the two countries .
