Irish authorities are investigating whether a second American woman was involved in a plot to kill a Swedish cartoonist for drawing an image of the Prophet Muhammad with the body of a dog.
Police say the woman was detained along with her Algerian husband and five other people Tuesday.
On the same day, the U.S. Justice Department announced the indictment of Colleen LaRose, who called herself "Jihad Jane" for plotting to kill a Swedish man, believed to be cartoonist Lars Vilks. LaRose is charged with conspiring to give material support to terrorists, conspiracy to kill in a foreign country, and other offenses.
Officials say at least some of the seven suspects arrested in Ireland had been in contact with LaRose.
Some information for this report was provided by AFP, AP and Reuters.
