Vatican City Pope Benedict XVI "sincerely regrets" offending Muslims with his reference to an obscure medieval text that characterizes some of the teachings of Islam's founder as "evil and inhuman," the Vatican said Saturday.
But the statement stopped short of the apology demanded by Islamic leaders around the globe, and anger among Muslims remained intense. Palestinians attacked five churches in the West Bank and Gaza over the pope's remarks Tuesday in a speech to university professors in his native Germany.
An Iraqi insurgent group threatened the Vatican with a suicide attack over the pope's remarks on Islam, according to a statement posted Saturday on the Web.
"We swear to God to send you people who adore death as much as you adore life," said the message posted in the name of the Mujahedeen Army on a Web site frequently used by militant groups. The message's authenticity could not be independently verified. The statement was addressed to "you dog of Rome" and threatens to "shake your thrones and break your crosses in your home."
In a broader talk rejecting any religious motivation for violence, Benedict cited the words of a Byzantine emperor who characterized some of the teachings of the Prophet Muhammad as "evil and inhuman," particularly "his command to spread by the sword the faith."
The pontiff did not endorse that description, but he did not question it, and his words set off a firestorm of protests across the Muslim world.
The new Vatican secretary of state, Cardinal Tarcisio Bertone, said the pope's position on Islam is unmistakably in line with Vatican teaching that says the church "esteems" Muslims.
Benedict "thus sincerely regrets that certain passages of his address could have sounded offensive to the sensitivities of the Muslim faithful and should have been interpreted in a manner that in no way corresponds to his intentions," Bertone said in a statement.
He noted that earlier during his German trip, Benedict warned "secularized Western culture" against holding contempt for any religion or believers.
Bertone said the pontiff sought in his university speech to condemn all religious motivation for violence, "from whatever side it may come." But the pope's words only seemed to fan rage.
Statement fails to satisfy
Bertone's statement, released Saturday by the Vatican press office, failed to satisfy critics, although British Muslim leaders said it was a welcome step.
Mohammed Bishr, a senior Muslim Brotherhood member in Egypt, said the statement "was not an apology" but a "pretext that the pope was quoting somebody else as saying so and so."
"We need the pope to admit the big mistake he has committed and then agree on apologizing, because we will not accept others to apologize on his behalf," Bishr said.
There was no indication whether the pope would do so. His first public appearance since his return from Germany was set for today, when Benedict planned to greet the faithful at Castel Gandolfo, the papal summer residence in the Alban Hills near Rome.
Morocco recalled its ambassador to the Vatican on Saturday to protest the pope's "offensive" remarks, and Afghanistan demanded the pope apologize.
Turkey cast some doubt on whether Benedict could proceed with a planned visit in November in what would be the pontiff's first trip to a Muslim nation.
Turkish Prime Minister Recep Tayyip Erdogan insisted the pope apologize to the Muslim world, saying he had spoken "not like a man of religion but like a usual politician."
Asked if Muslim anger would affect the pope's trip to Istanbul, where he hopes to meet with Orthodox leaders headquartered there, Erdogan replied, "I wouldn't know."
Turkey's top Islamic cleric, Religious Affairs Directorate head Ali Bardakoglu, welcomed the Vatican statement.
"He says that he respects Islam and didn't want to hurt the feelings of Muslims. I find that a civilized position," said Bardakoglu in an interview posted on the Web site of Germany's Der Spiegel magazine.
Ecumenical Patriarch Bartholomew I, spiritual leader of the world's 200 million Orthodox Christians, issued a statement saying he was deeply saddened by the tensions sparked by the pope's comments.
"We have to show the determination and care not to hurt one another and avoid situations where we may hurt each others' beliefs," the Istanbul-based Patriarchate said.
In West Bank attacks on churches, Palestinians used guns, firebombs and lighter fluid, leaving church doors charred and walls scorched by flames and pocked with bullet holes. Nobody was reported injured. Two Catholic churches, an Anglican one and a Greek Orthodox one were hit. A Greek Orthodox church was also attacked in Gaza City.
A group calling itself "Lions of Monotheism" told The Associated Press by phone that the attacks were a protest against the pope's remarks on Islam.
During his speech, Benedict stressed that he was quoting words of a Byzantine emperor and did not comment directly on the "evil and inhuman" assessment. On Saturday, Bertone said that "the Holy Father did not mean, nor does he mean, to make that opinion his own in any way."
Benedict quoted from a book recounting a conversation between 14th century Byzantine Christian Emperor Manuel Paleologos II and an educated Persian on the truths of Christianity and Islam.
"The emperor comes to speak about the issue of jihad, holy war," the pope said. "He said, I quote, 'Show me just what Muhammad brought that was new, and there you will find things only evil and inhuman, such as his command to spread by the sword the faith he preached."'
The grand sheik of Cairo's Al-Azhar Mosque, the Sunni Arab world's most powerful institution, condemned the pope's remarks as "reflecting ignorance."
The Shiite Muslim militant group Hezbollah and Lebanon's top Sunni Muslim religious authority also denounced the pope's comments.
British Muslims sought to calm the situation.
"We welcome his apology and we hope now we can work together and build bridges. At the same time we would condemn all forms of violent demonstration," Muhammad Umar, chairman of Britain's Ramadhan Foundation, a youth organization, told Sky News.
