India has filed an appeal against the death penalty given to eight former Indian Navy personnel by a Qatar court last month. A court in Qatar had last month sentenced Captain Navtej Singh Gill, Captain Birendra Kumar Verma, Captain Saurabh Vasisht, Commander Amit Nagpal, Commander Purnendu Tiwari, Commander Sugunakar Pakala, Commander Sanjeev Gupta and Sailor Ragesh to death after finding them guilty of 'spying for Israel' while working for private company Al Dahra on a naval project in Qatar.
