**A Pennsylvania woman held over an alleged overseas terrorism plot has pleaded not guilty to four charges.**Colleen LaRose, who allegedly called herself Jihad Jane, denies conspiring with Islamists and pledging to murder in the name of a Muslim holy war.
The 46-year-old was indicted as part of an investigation into an alleged plot to kill a Swedish cartoonist who drew pictures of the Prophet Muhammad.
She was arrested in October 2009 in Philadelphia.
The accused, also known as Fatima LaRose, appeared in a Philadelphia federal court wearing a green jumpsuit and with corn-row braids in her hair.
Authorities say she posted a YouTube video in 2008, saying she was “desperate to do something” to ease the suffering of Muslims.
Her indictment was part of an international investigation into an alleged plot to kill Swedish cartoonist Lars Vilks, who drew the Prophet Muhammad with the body of a dog.
Ms LaRose was charged on Tuesday of last week, on the same day as seven Muslims were detained in the Irish Republic.
Five of them, including a Colorado woman, Jamie Paulin-Ramirez, have been freed without charge.
Two others, an Algerian and a Libyan, have been charged with sending a menacing text message and an immigration offence respectively.
Mr Vilks’ controversial cartoon was used in a 2007 Swedish newspaper editorial on freedom of expression.
A group linked to al-Qaeda in Iraq later offered a cash reward for killing him, with a bonus if his throat was cut.
