Pope Benedict XVI is continuing to face demands from the Muslim world to apologize for his controversial comments about Islam.
Turkish workers from a religious affairs union demonstrated in Ankara Tuesday, demanding the pope apologize or cancel his planned trip to Turkey.
Some of the protesters called for the arrest of the pontiff when he visits the predominantly Muslim country in late November.
But Turkey's government says it expects the trip to go ahead on schedule.
Meanwhile, the Vatican says it is sending envoys to meet with Muslim world leaders to explain last week's speech in Germany.
The pope has said his comments did not reflect his personal views, and he expressed regret for the Muslim world's outrage. The pontiff had quoted a 14th century Byzantine emperor who said some of the teachings of the Prophet Muhammad were evil and inhumane.
Malaysian Prime Minister Abdullah Badawi says his country accepts the pope's expressions of regret, but he urged the Roman Catholic leader to refrain from making statements that could anger Muslims further. Malaysia chairs the Organization of the Islamic Conference, the world's biggest Muslim bloc.
During a meeting with Mr. Badawi in New York Monday, President Bush said he thinks the pope was sincere in his regret.
Despite the Vatican's repeated apologies for misunderstandings caused by the speech, many Muslims have equated what the pope said with what they think he believes.
