Militants have killed at least six truck divers who were trying to supply goods to the besieged Shia Muslims in Pakistan's northwestern town of Parachinar. Pakistani police found the dead bodies on Saturday in the nearby restive northwestern Thal district.
"A letter found in the pocket of one dead truck driver said that if anyone supplied goods to the Parachinar Shia community, he will be treated like this," local police official Abdul Rehman told AFP.
The drivers were kidnapped a few days ago on their way to Parachinar, the main town of Kurram tribal district.
Shia Muslims in Pakistan's Kurram Agency have been facing a serious humanitarian crisis since November 2007, when pro-Taliban militants cut off the area from the rest of the country.
They have imposed a crippling blockade on the Shia communities in the region since then.
Local sources say more than 2,000 Shia Muslims have been killed in the region since the extremists launched a bloody campaign against them two years ago.
