JORDAN-JAPAN-SYRIA-CONFLICT-HOSTAGE-DEMO

Relatives of Jordanian air force pilot Maaz al-Kassasbeh, who crashed in Syria with a F-16 last month, carry posters with his portrait and a slogan reading in Arabic, "we are all Maaz", during a protest near the Prime Minister office in Amman late on January 27, 2015 demanding the release of Sajida al-Rishawi, an Iraqi female suicide bomber on death row in Jordan . The Islamic State jihadist group threatened yesterday to kill a Japanese journalist and a Jordanian pilot within 24 hours unless Amman frees the jailed female Iraqi militant.
