The parents of James Foley, the American journalist killed by Islamic State militants in Iraq, on Friday called for prayer and support to free the remaining captives held by Islamic State fighters. "We do pray, we beg the international community to help the remaining hostages," his mother, Diane Foley, said in an interview with her husband, John, on MSNBC. "We just pray that they will be set free." Their plea comes after a long conversation with Pope Francis, who the Vatican said called the couple on Thursday afternoon to offer his condolences and support. James Foley, who was abducted in Syria in late 2012, was beheaded by a masked member of the Islamic State group in an act filmed in a video released on Tuesday that also threatened a second American journalist, Steven Sotloff.
