An Afghan has avenged the killing of his brother by gunning down three suspected Uzbek terrorists on February 17 in North Waziristan Agency, a senior official said on Saturday. The body of an Afghan national identified by his killers as Wasayel Shah was found on main Miranshah-Bannu Road near Mir Ali town on February 14. A message was also found with the body reading that Shah was spying on "mujahideen" for the United States. "The Thursday killing of three foreigners in the Kurram Kot area was a revenge by the brother of Wasayel Shah," the official told Daily Times requesting not to be named. There were conflicting reports from the region after the mysterious killing of the three foreigners. One of the reports said that a group of men had opened fire at the foreigners while the second report said the Afghan, who escaped arrest after sheltering in a village, gunned down the three Uzbeks on his own. "It was Wasayel Shah's brother who killed the three foreigners," the official said.
