A Norwegian court has sentenced an Iraqi-born cleric to 18 months in jail for praising the slaying of cartoonists at the French satirical Charlie Hebdo newspaper that had lampooned Islam and other religions.

The Oslo city court also found Najmaddin Faraj Ahmad, known as Mullah Krekar, guilty of urging others to kill a Kurdish immigrant in Norway in the same interview with Norwegian broadcaster NRK.

In that interview, he said a cartoonist is "a fighting heathen whom it is permissible to kill."

Earlier this year, Ahmad was freed after nearly three years imprisonment for making death threats. The 59-year-old Kurd, who came to Norway as a refugee in 1991, was convicted in 2005 for a similar offense.

His lawyer, Brynjar Meling, saus they have not decided whether to appeal.
