Three employees of an oil and gas exploration company and their paramilitary escort were kidnapped and shot dead Tuesday in a restive Pakistani tribal region near the Afghan border, officials said.
"The employees and their escort, an official of Frontier Corps, were heading towards their office when kidnapped by unknown gunmen," a senior local administration official told AFP on condition of anonymity.
He said their bullet-riddled bodies were found near Spinwam late in the afternoon.
A local intelligence official also confirmed the incident and fatalities and said it was unclear where the gunmen were from as no group has so far claimed responsibility for the incident.
Violence in Pakistan has declined dramatically in recent years following a series of military operations along the northwestern border with Afghanistan, but militant groups are still able to carry out deadly attacks.
