Four men acquitted in the kidnapping and killing of American journalist Daniel Pearl in Pakistan have been rearrested and will stay in jail while prosecutors appeal the ruling, officials said. A Pakistani court sparked US outrage on Thursday after it quashed the murder conviction of British-born militant Ahmed Omar Saeed Sheikh who had been on death row over the 2002 killing. Three alleged accomplices also had their convictions overturned. But Pakistan's interior ministry said late Friday the four would remain in jail while prosecutors appeal their acquittals in the country's Supreme Court. Pearl, 38, was the South Asia bureau chief for The Wall Street Journal when he was abducted in Karachi in January 2002 while researching a story about Islamist militants. A graphic video showing his decapitation was delivered to the US consulate in the city nearly a month later.
