ISLAMABAD , Pakistan ( CNN ) -- Pakistani security forces say they have killed at least 16 militants overnight in the country 's volatile tribal region . Pakistani security personnel patrol the Buner district . This appears to be separate from the hostilities in the military 's week-long crackdown in northwestern Pakistan against a Taliban militant advance in the country 's North West Frontier Province . However , this reflects the tensions in the region and could signal a spread of fighting resulting from the crackdown . The Pakistani offensive started in the province on Sunday and it came after Taliban militants moved into Buner district last week , a move that alarmed U.S. and Pakistani officials . In this latest incident , about 100 militants attacked a Frontier Corps checkpost in the Mohmand Agency , 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 borders a volatile region in war-torn Afghanistan and Pakistan 's North West Frontier Province . The military on Saturday released details about other incidents in the province that occurred over the last 24 hours . Troops conducted a successful operation against militants in the district , in the Ambela-Daggar area in the Buner district . They secured a key road and cleared roadside bombs , the military said . In the province 's Upper Dir district , militants abducted and then released 10 troops and seized their weaponry and ammunition . And two civilians were wounded when militants lobbed hand grenades . In the province 's Swat district , militants attacked a security forces checkpost on Khawazakhela Bridge and Sambat Ridge . In Langer , security forces and militants exchanged fire and forces found military uniforms that militants were using for terrorist activity . Three Afghan nationals were among five militants arrested while planting a roadside bomb . Earlier this year , Pakistan entered into an agreement with militants , allowing them to enforce Islamic , 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 both 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 .
