BBC, France 24 and Voice of America are also among the broadcasters affected by the jamming.
The satellite provider Arabsat has identified Ethiopia as the source of the strong jamming signals on all its three satellites. Ethiopian authorities have not responded to the incident yet.
Peter Limbourg, director general of Deutsche Welle: "This is a gross violation of the internationally recognized right of freedom of speech and freedom of the press. Deutsche Welle, BBC, France 24 and Voice of America strongly condemn this action against the free flow of impartial information. We urge the Ethiopian authorities to immediately cease the jamming."
While Deutsche Welle's short wave programs have been repeatedly target of jamming from Ethiopia, the current incident appears not to be aimed at specific broadcasters or programs. The jamming of satellite programs constitutes a violation of international agreements, but the practice is nevertheless on the rise. The most recent incidents occurred in 2011 and 2012 via Iran.
In the Arab world Deutsche Welle is available through its TV channel "DW Arabia." Selected radio programs in Arabic are available via partner stations throughout the region.
