Islamabad, Pakistan (CNN) -- Authorities in Pakistan's tribal region believe the Taliban have abducted around 30 young people on an outing there.

Islam Zeb, a senior administrator in Bajaur Agency, told CNN on Friday the people were between the ages of 10 and 20 and elders were meeting to discuss the recovery of the children.

Zeb said the youth were walking to a picnic spot along a river to mark the end of the Muslim holiday of Ramadan.

Members of the Tehrik-e-Taliban Pakistan contacted relatives and said they were holding the youth, Zeb said.

Bajaur Agency, which lies along the porous border with Afghanistan, is one of seven districts in Pakistan's tribal region.

This abduction comes days after a cross-border attack by militants from Afghanistan, which killed 25 Pakistani security personnel in Chitral, a mountainous region in northern Pakistan.
