Islamabad: Tehrik-e-Taliban Pakistan (TTP) on Saturday claimed responsibility for kidnapping a group of over 30 boys, who had strayed into Afghanistan's eastern Kunar province as reports said some of them had escaped and reached back to their homes.

The fate of children would be decided by TTP's central council, the group's spokesman Ehsanulah Ehsan said claiming that they had kidnapped the youth as their parents were helping the Pakistan army in their drive against it.

Their kidnapping has raised fears that the children might be used as suicide bombers.

The terror group said they were "anxiously waiting" for the Pakistani children from Bajaur tribal region to come to the mountains for celebration of Eid.

Children from Bajaur tribal region, who had gone for picnic to celebrate 'Eid' had mistakenly crossed into bordering Kunar province on Thursday.

The group is holding 25 children aged 18 to 20 as hostages, Ehsan said. However, Pakistani officials said the boys are aged between 10 to 15.

Officials had earlier said that over 30 children were held hostage by militants.

Sources said that several children escaped and reached back to their homes.

The Taliban spokesman said that parents of the hostage youth are pro-government tribesmen and have formed committees against the Taliban, who had fled Bajaur tribal region after the major military offensive in 2008-09.

Ehsanullah said the Taliban's central 'Shura' or council will decide fate of the youth and the council has started identification process of the hostages.

Officials said that many children from the major Mohmand tribe had gone for picnic in the mountainous areas and mistakenly crossed into Afghanistan as there is no determined border in the area. Members of Mohmand tribe live on both sides of the border.

Afghanistan calls it Durand Line and does not accept it as an official border.

Officials say that nearly 100 children had crossed the border but dozens succeeded to escape when Taliban were trying to take them hostage.

Pakistan army says that members of Pakistani Taliban have now established bases in Kunar and Nuristan provinces of Afghanistan and also launch attacks on Pakistani posts from their bases in the Afghan border regions.

Army spokesman Major General Athar Abbas said that the TTP's deputy chief Maulvi Faqir, who belonged to Bajajur, has regrouped his fighters in Kunar.

He is being sheltered by an Afghan militant leader Qari Zia-ur-Rahman, who lived for years in Bajaur with Faqir's support.

A jirga of the main Mamond tribe is also underway to explore ways to rescue the children.

Tribal elders also asked the local administration to step up efforts for the early release of the children.

Local media reported that the hostage children could be used for suicide bombings if the government and tribal elders failed to secure the release of the children.
