A Swedish citizen was sentenced to six months in jail Thursday (February 23rd) for inciting people to finance the "Islamic State of Iraq and the Levant" (ISIL) via Facebook, AFP reported.

In a Facebook account linked to Ahmad Qadan, 34, a post written in Swedish and published on August 21, 2013 said: "Help us supply our brothers at the front with weapons so they can avenge their brothers and sisters."

Malmo district court judge Lennart Strinas said the case had no precedent in Sweden.

"The crime that the man has been convicted of might have been at an early stage in the chain of events but it could have led to a terrorist crime," he said.

Those who read the post were urged to call two named men to receive a bank account number where money could be sent, the court said. One of the named men in the post is listed as a terror financier by the UN and the EU.

The posts "had been published in such a way that anyone with access to the Internet could read them, even people without a Facebook account", the court said.

Around 300 people have left Sweden to fight with extremist groups in Syria and Iraq, according to Swedish intelligence agency Sapo.
