According to amendments added in the 1980s, “Use of derogatory remarks, etc; in respect of the Holy Prophet; whoever by words, either spoken or written or by visible representation, or by any imputation, innuendo, or insinuation, directly or indirectly, defiles the sacred name of the Holy Prophet Mohammed shall be punished with death, or imprisonment for life, and shall also be liable to fine.”
Pakistan Christian Congress (PCC), a political party launched by Pakistani Christians, has blamed the 1986 blasphemy law for the violence against the Christian community. “On several occasions, on the pretext of blasphemy, Christians have been attacked, pastors and priests arrested, women raped and homes burnt," PCC has said.
