ISLAMABAD -- Casualties were reported as fighting between Tehrik-i-Taliban (TTP) and Ansar-ul-Islam militant groups entered its fourth day in Pakistan's Khyber tribal district near the Afghan border.
Pakistani media says at least six insurgents were killed on January 28 in the latest clashes between the two banned Islamic militant groups.
It remains unclear how many casualties each group has suffered.
