Local Pakistani officials say suspected militants have abducted more than 30 Pakistani boys, after they crossed into neighboring Afghanistan.

Officials say the boys, between the ages of 10 and 18, were kidnapped Thursday after crossing from Pakistan's Bajaur tribal region into Afghanistan's eastern Kunar province.

Local authorities in Afghanistan said they had no knowledge of the abduction.

The porous border region between Pakistan and Afghanistan is a known safe haven for al-Qaida and Taliban-linked militants.

Last month, Pakistani leaders protested deadly cross-border attacks on Pakistan's tribal region by militants who crossed into Pakistan from Afghanistan.
