ISLAMABAD: Imran Khan, chief of the Pakistan Tehreek-i-Insaf, said on Monday that some elements, including the United States, were against peace in the country and an operation in Waziristan region was not in favour of Pakistan, DawnNews reported.

He also called on the government to identify those behind anti-state conspiracies, adding that enemies of Pakistan were sheltering those behind attacks such as the one carried out in Islamabad today.

Talking about a full-fledged operation in North Waziristan tribal region, Khan said it was not in Pakistan's favour and action should be taken only against those militants who did not want to carry out peace talks.

He also said that an operation in Wazrisitan would greatly damage the country.

The Tehreek-i-Taliban Pakistan has announced a one-month ceasefire which was followed by the government's statement that it would halt air strikes conducted against militants and their hideouts.

The developments took place after a deadlock was reached between government and Taliban negotiators.
