Pakistan's government on Friday petitioned the Supreme Court to review its decision to free an Islamist and his co-accused convicted of kidnapping and beheading US journalist Daniel Pearl, the Pearl family's lawyer Faisal Siddiqi said.
The court on Thursday acquitted British-born Ahmad Omar Saeed Sheikh and his co-accused, who had been convicted in 2002.
Pearl was investigating Islamist militants in Karachi when he was killed.
