Islamabad , Pakistan ( CNN ) -- The Pakistan Taliban said Wednesday it will not extend a cease-fire with the Pakistani government , six days after a weeks-long pause in hostilities officially ended . In a statement released to the news media , the Tehrik-e-Taliban Pakistan , or TTP , alleged the Pakistani government had n't responded positively to the cease-fire , which began as a monthlong observance on March 1 and eventually was extended to April 10 . One of the militant group 's leaders , Umer Khalid Khurrsani , said Wednesday that the government was n't serious about peace and that the only way to implement Sharia , Islamic law , was jihad . The group made a series of demands this month , including the release of detained noncombatants . Pakistan 's government has not yet issued a response to the announcement , Interior Ministry spokesman Danial Gillani said Wednesday . The TTP has waged an insurgency against the Pakistani government , fighting for its austere version of Sharia across Pakistan and rejecting the country 's constitution . Pakistan announced a peace initiative , and a cease-fire was reached to pave the way for talks , but discussions broke down in March after Taliban attacks . Pakistani government representatives did meet the Taliban for talks on March 26 , the first direct contact between the two sides . The Taliban had made demands , including the release of noncombatants , in early April . At least 19 Taliban noncombatants were released earlier as a good will gesture to promote peace talks , said Shaukatullah Khan , governor of Khyber-Pakhtunkhwa province . The release came at the directive of Pakistani Prime Minister Nawaz Sharif , Khan said . Since taking office last year , Sharif faced mounting pressure to bring the violence under control .
The cease - fire was signed upon April 3 and officially was in effect until April 10 . Pakistani government officials met with the Taliban last week to promote peace . The militant group had demanded the release of prisoners .
