(Compass) – Pastor Oqbamichel Haimanot of the Kale Hiwot (Word of Life) Church, arrested four months ago at a wedding, has suffered a mental breakdown due to harsh physical and emotional mistreatment suffered during his confinement at the military training center in Sawa. The evangelical minister, arrested January 9 along with 64 church members, is one of 16 pastors and nearly 900 Eritrean Christians jailed for meeting to pray and worship without government approval. None of the prisoners have been charged in court or brought to trial. Eritrean Christians have expressed particular concern for vulnerable prisoners. They include Orthodox Church leader Dr. Tekleab Mengisteab, who has been unable to obtain the medications for his diabetic condition, and Demoze Afwerki, 67, who heads Gideons International in Eritrea .
