What is eritrea's president religion?

President Isaias Afewerki is from an Orthodox Christian family and from this everyone can assume he is a Christian.

However, his Maoist political culture and the fact that he has turned the country into one of the world's worst persecutors of christian faith (including arresting Eritrean Orthodox Patriarch incommunicado for over 8 years) can be taken to suggest he is not a terribly devout Christin.
