Two young Christians, a pastor and his brother, were killed on court premises in Faisalabad, Pakistan.
A police officer was escorting the men when an unidentified gunman killed them.
The brothers faced charges for blasphemy against Islam after handwritten pamphlets said to denigrate Islam were found.
The brothers' names and phone numbers were listed on the pamphlets.
Christian groups in Pakistan say the blasphemy law often is misused against Christians.
