Salwan Momika, a Christian Iraqi who burned Korans at a slew of protests in Sweden over the summer, told AFP that he had left Sweden and arrived in Norway, where he planned to seek asylum.

"I left Sweden because of the persecution I was subjected to by government institutions," Momika said in a text message.

Momika's Koran burnings sparked widespread outrage and condemnation in Muslim countries.

Iraqi protesters stormed the Swedish embassy in Baghdad twice in July, starting fires within the compound on the second occasion.

The Swedish government condemned the desecrations of the Koran but stressed the country's laws regarding freedom of speech and assembly.

Sweden's intelligence agency heightened its terror alert level in mid-August to four on a scale of five after the angry reactions made the country a "prioritised target".

The Swedish Migration Agency revoked Momika's residency permit in October, citing false information in his original application, but he was granted a temporary one as it said there were was an "impediment to enforcement" of a deportation to Iraq.

The month before, Iraq had requested his extradition over one of the Koran burnings.

"Sweden has become a threat to me after the decision to expel me and the threat to extradite me to Iraq," Momika said.

Momika called Sweden's freedom of expression and protection of human rights "a big lie."
