The Taliban

The Taliban released a videotape of the beheading of Polish engineer Piotr Stanczak. The Taliban murdered Stanczak after the Pakistani government refused to release 60 Taliban fighters. Before he was beheaded, Stanczak appealed for Poland to withdraw from Afghanistan and cut ties with Pakistan.
