The AP reports:

Nigerian Muslims protesting caricatures of the Prophet Muhammad attacked Christians and burned churches on Saturday, killing at least 15 people in the deadliest confrontation yet in the whirlwind of Muslim anger over the drawings.

It was the first major protest to erupt over the issue in Africa's most populous nation. An Associated Press reporter saw mobs of Muslim protesters swarm through the city center with machetes, sticks and iron rods. One group threw a tire around a man, poured gas on him and set him ablaze. . . .

Thanks to InstaPundit for the pointer.

The one bright spot in this story comes in a quote from a Danish bishop, in a telling exchange with an Egyptian imam:

In Cairo, Bishop Karsten Nissen, of Denmark's Evangelical Lutheran Church, met with Grand Imam Mohammed Sayyed Tantawi of al-Azhar University, the world's highest Sunni Muslim seat of learning.

Tantawi said the Danish prime minister must apologize for the drawings and further demanded that the world's religious leaders meet to write a law that "condemns insulting any religion, including the Holy Scriptures and the prophets." He said the United Nations should impose the law on all countries.

In response, Nissen did not address the issue of a global law but said it was impossible for Prime Minister Anders Fogh Rasmussen to apologize.

"I have brought to his excellency (Tantawi) the apology of the newspaper, but our prime minister did not draw these cartoons. Our prime minister is not the editor of this newspaper. He cannot apologize for something he did not do," Nissen said....

I'm glad that even against the backdrop of murderous thuggery by Muslim extremists, some people are willing to repeat that, no, free nations and governments are not responsible for what their newspapers publish.
