Car bomb kills six at embassy in Pakistan.

A MASSIVE car bomb planted in revenge for Denmark's continued defiance in the Islamic cartoon row killed at least six people at its Pakistan embassy yesterday.

It was the worst attack since Danish newspapers printed the caricatures of the prophet Mohammed two years ago.

Prime Minister Anders Fogh Rasmussen called the bombing "an attack against Denmark."

But he said they would not be cowed by terrorists.

"Denmark will not alter its policy because of a terror attack. We will not give in to terrorists."

Earlier this year Danish intelligence officials warned of an "aggravated" terror threat against Denmark after local newspapers reprinted a cartoon of Mohammed wearing a bomb-shaped turban. Islamic law generally opposes any depiction of the prophet for fear it could lead to idolatry.

The cartoon was one of 12 featuring the prophet that sparked riots in the Muslim world in 2006. Mobs attacked Danish embassies in Lebanon, Syria and Iran to protest against publication of the cartoons in European newspapers.

Foreign Minister Per Stig Moeller said the bomb killed an embassy cleaner and injured three other embassy workers, none of them Danes. He said the government did not know who was behind the blast.

Denmark withdrew its troops from Iraq last year but has more than 600 soldiers in Afghanistan.
