The controversial drawing by Swedish artist Lars Vilks was printed in Stockholm papers Dagens Nyheter and Expressen and the Malmo daily Sydsvenska Dagbladet.
Irish authorities had said on Tuesday they detained four men and three women suspected of involvement in an alleged plot to kill Vilks.
Sydsvenska Dagbladet said it printed the drawing as part of its news coverage of the alleged plot. Expressen said it printed it for its news value and to take a stance for the freedom of speech.
Dagens Nyheter said in an editorial that “Vilks doesn’t stand alone in this conflict. A threat against him is, in the long term, also a threat against all Swedes.”
Vilks has faced several death threats since the drawing was first printed by a Swedish newspaper in 2007, a year after separate cartoons of Muhammad in a Danish newspaper sparked furious protests in Muslim nations. Al-Qaeda put a $US100,000 ($A109,470) bounty on his head.
