Muslims have staged fresh protests in the row over cartoons of the Prophet Muhammad, as Denmark - where the row started - made a new bid to calm anger.
Anti-Danish protests have been staged in Baghdad and other cities
Danish PM Anders Fogh Rasmussen called in Muslim ambassadors to explain his position over the images' publication.
He said he could never apologise for a newspaper's actions but said he was "distressed" at offence caused.
The cartoons, some of which depict the Prophet as a terrorist, have angered Muslims who regard them as blasphemous.
However, more European papers have printed the cartoons, citing free speech.
Mr Rasmussen met ambassadors in Copenhagen on Friday - something he had refused to do when the matter arose after the cartoons first appeared in September.
Afterwards he said: "Neither the Danish government nor the Danish nation as such can be held responsible for drawings published in a Danish newspaper.
"A Danish government can never apologise on behalf of a free and independent newspaper. This is basically a dispute between some Muslims and a newspaper."
He has said the issue has gone beyond Denmark to become a clash between Western free speech and Islamic taboos.
Fresh Muslim protests flared on Friday in a number of countries over the cartoons, one of which shows the Prophet wearing a headdress shaped like a bomb.
Another shows him saying that paradise is running short of virgins for suicide bombers.
Islamic tradition bans depictions of the Prophet or Allah.
In the Indonesian capital, Jakarta, dozens of protesters from the Islamic Defenders' Front forced their way into a high-rise building housing the Danish embassy.
Demonstrators were prevented from reaching the embassy itself, on the 25th floor.
The incident happened after an Indonesian newspaper posted the cartoons on its website. It was later forced to take them down.
There were other protests in Iraq, Egypt and the Turkish cities of Diyarbakir, Konya and Istanbul.
However, other European newspapers have now printed the cartoons.
French daily Liberation and Belgian paper De Standaard published them, along with the Irish Daily Star, which called Muslim protests "entirely unwarranted and hateful".
