"""A masked person holding a knife speaks as he stands in between two kneeling men in this still image taken from an online video released by the militant Islamic State group on January 20, 2015. The militant Islamic State group released the online video on Tuesday purporting to show two Japanese captives and threatening to kill them unless it received $200 million in ransom. The black-clad figure with the knife, standing in a barren landscape along with two kneeling men wearing orange clothing, said the Japanese public had 72 hours to pressure their government to stop its """"foolish"""" support for the U.S.-led coalition waging a military campaign against Islamic State. The militant, who spoke in English, demanded """"200 million"""" without specifying a currency, but an Arabic subtitle identified it as U.S. dollars. The footage named the men as Haruna Yukawa and Kenji Goto.  REUTERS/Social media website"""
