They said that TTP spokesman Shahidullah Shahid would make the announcement of the possible ceasefire decision.It has also been learnt that TTP has contacted Samiul Haq on the possible ceasefire. The sources added that there are bright chances that two members of government negotiation committee may leave for Miranshah to hold talks with Taliban shura directly, adding that this meeting may take place in next two days for 'direct dialogue' in which ceasefire announcement is highly likely.

Outmost desire is to announce a ceasefire between TTP and government adding that it was a demand of the whole nation and it should be done very first. In this regard, he said the nation would soon hear good news soon.He was much optimistic that talks would succeed adding those who wanted to sabotage the process would fail at all.

He said that the government and Taliban negotiation committees have expressed their concerns over the terrorist incidents in Karachi and Peshawar. Similarly, member of government negotiation committee Rustam Shah Mohmand Sunday said that this stage of dialogue was extremely crucial and it would be difficult to proceed without complete ceasefire on both sides. Talking to journalists he said that the time is very short and there are a lot of decisions to be taken by Taliban and government and without ceasefire it would be impossible to take these serious decisions. He said that government would definitely announce ceasefire if Taliban stops their activities in the country.Rustam assured that both military and civilian leadership have unanimously opted the way of dialogue and both of them are on the same page in this connection. He said that so far army has played very positive role in dialogue process. He added that if Taliban are serious for dialogue then they should consider their request for ceasefire. He informed that they have the panacea to resolve the matter of Taliban and government detainees.Government and Taliban-nominated committees have held preliminary talks aimed at ending the decade-long insurgency that has claimed some 40,000 lives. However, there is growing scepticism that the process will produce a lasting solution, with observers pointing out that the Taliban have reneged on all past peace deals.The TTP has carried out several terrorist attacks even after joining the peace process. Government negotiators had earlier this week made it clear that further attacks would not be tolerated. They had said that if attacks continued, "it would become difficult to continue the dialogue process". Prime Minister Nawaz Sharif has also expressed concern over these attacks as Taliban have taken responsibility for Karachi and Peshawar attacks.This news was published in The Nation newspaper.
