German authorities have released Al Jazeera journalist Ahmed Mansour, who had been detained at Berlin airport at the request of the Egyptian government.

Accompanied by his lawyers, Mansour greeted his supporters after his release on Monday, and thanked the German court for its decision.

"I extend my thanks and appreciation to the honest and honourable judges of Germany," he said in Arabic.

"Thanks to people around the world who supported me in the last days," Mansour added. "I'm free, I'm free, I'm free."

Earlier reports had said a court in Germany was about to consider Egypt's request to extradite Mansour, one of the Arab world's most respected journalists.

Al Jazeera's Paul Brennan, reporting from Berlin earlier, said a temporary detention investigative judge concluded his investigation with Mansour on Sunday, after which he was transferred to Moabit prison in Berlin.

Our correspondent said that the court and Mansour's lawyers were "making the arrangements for his departure."

Saad Djebbar, one of Mansour's lawyer, said that while his client was "very happy" about the court's decision, he was also "very said" that the Al Jazeera journalist was detained in the first place.

Another lawyer, Patrick Teubner, said that with the court decision, Mansour could now leave Germany.
