UNIMAID lecturer currently in Boko Haram captivity writes to his wife, laments FG's failure to rescue him and other lecturers

Dr. Solomon Yusuf who is one of the four University of Maiduguri (UNIMAID) lecturers abducted by suspected Boko Haram terrorists in Magumeri, Borno State on July 25th in Borno state, has written a letter to his wife, Hannatu, lamenting the failure of Federal Government to ensure their release from Boko Haram captivity.
Recall that Yusuf and three other lecturers were ambushed and kidnapped while obtaining soil samples for hydrocarbon exploration around the Chad Basin. The exploration was being coordinated by the Nigerian National Petroleum Corporation (NNPC).                
The lecturer's lamentation was contained in a letter from captivity sent to his wife, Hannatu which was obtained by SaharaReporters. Part of the letter reads

"I want to emphasize that delay in getting our freedom poses risk to our dear lives. We never expected we would spend over 42 days (as at 4 September) in captivity because the project has presidential orders to explore hydrocarbon in the Chad BasinThe government should please continue negotiating with the present contact given to them by the University of Maiduguri as a means of contacting soldiers of Khalifa under the leadership of Abu Mus'ab Albarnawi. We plead with the government to treat our freedom with all sense of urgency and sympathy so that that we can be reunited with our families. The use of force is a serious threat to our lives," he pleaded.
