a referendum approved the constitution for the PDRE, it was not until September that the new government was fully in place and the Derg formally abolished. The surviving members of the Derg, including Mengistu, remained in power as the leaders of the new civilian regime. The geopolitical situation became unfavourable for the communist government in the late 1980s, with the Soviet Union retreating from the expansion of Communism under Mikhail Gorbachev's glasnost and perestroika. Socialist bloc countries drastically reduced their aid to Ethiopia and were struggling to keep their own economies going. This resulted in even more economic hardship, and the military gave way in the face of determined onslaughts by guerrilla forces in the north. The Soviet Union stopped aiding the PDRE altogether in December 1990. Together with the fall of Communism in the Eastern Bloc in the Revolutions of 1989, this itself dealt a serious blow to the PDRE. Towards the end of January 1991, a coalition of rebel forces, the Ethiopian People's Revolutionary Democratic Front (EPRDF) captured Gondar (the ancient capital city), Bahir Dar and Dessie. Meanwhile, the Eritrean People's Liberation Front had gained control of all of Eritrea except for Asmara and Assab in the south. The Soviet Union, mired in its internal turmoil, could no longer prop up the Derg. In the words of the former US diplomat Paul B. Henze, "As his doom became imminent, Mengistu alternated between vowing resistance to the end and hinting that he might follow Emperor Tewodros II's example and commit suicide." His actions were frantic: he convened the Shengo, for an emergency session and reorganized his cabinet, but as Henze concludes, "these shifts came too late to be effective." On 21 May, claiming that he was going to inspect troops at a base in southern Ethiopia, Mengistu slipped out of the country into Kenya. From there, he flew along with his immediate family to Zimbabwe, where he was granted asylum and where he still resides. Mengistu was sentenced to death in 2008 in absentia, charged with genocide, homicide, illegal imprisonment and property seizures. In 2009, Zimbabwe’s late former Information Minister, Tichaona Jokonya, in an interview with Voice of America said Harare was not going to extradite Mengistu. In August 2018, Ethiopian former Prime Minister Hailemariam Desalegn while heading an African Union election observer mission in Harare met with Mengistu, and shared their photo on Facebook, which was quickly deleted
