Foreign Minister Frank-Walter Steinmeier has vowed that Germany will do all in its power to resolve the fate of the blogger condemned to 1,000 lashes in Saudi Arabia.
"The penalty handed down to Raef Badawi is cruel, bad, unjust and totally disproportionate," Steinmeier said in comments to appear Sunday in the Bild am Sonntag weekly newspaper.
The German Foreign minister was lending his voice to a case which has already prompted worldwide outrage and criticism from the UN, US, the EU and others.
Rights group Amnesty International said Thursday that Saudi Arabia had decided to postpone Badawi's next session, for a second week on medical grounds.
The 30-year-old Saudi has been sentenced to 1,000 lashes for insulting Islam and is serving a 10-year jail term.
He received the first 50 lashes of his sentence outside a mosque in the Red Sea city of Jeddah on January 9.
"You can be sure that we will continue to do everything we can to promote a solution," to the Badawi case, Steinmeier said, adding that "the question of human rights plays a very important role in discussions between Berlin and Riyadh, even outside of this matter."
Badawi's wife Ensaf Haidar, who has sought asylum with her children in Canada, told AFP by telephone that her husband's case has been referred to the supreme court, possibly paving the way for an appeal.
Badawi co-founded the now-banned Saudi Liberal Network along with women's rights campaigner Suad al-Shammari, who was also accused of insulting Islam and arrested last October.
The charges against Badawi were brought after his group criticised clerics and the kingdom's notorious religious police, who have been accused of a heavy-handed enforcement of sharia Islamic law.
